$19995       The  "BLACK  BOX"!©        $19996 

The  Black  Box  is  a  device  for  your  XL  or  130XE  computef  that 
adds  tremendous  power  to  your  8-bit  Atari  It  has  two  buttons, 
two  switches,  and  o  set  of  dip  switches  visible  from  the  outside.  It 
plugs  directly  into  the  back  of  the  600XL,  800XL,  and  130XE 
computers.  Custom  cases  may  be  on  optional  expense.  The 
Black  Box  performs  three  main  tasks:  interface  to  a  SASl/SCSI  bus 
device  (hard  disks).  Parallel  printer  port,  and  a  f?S232  port.  A 
fourth  option,  available  soon,  will  be  a  floppy  disk  porl,  especially 
useful  to  XF-551  owners.  The  SASl/SCSI  port  provides  the 
necessary  signals  for  hooking  up  most  common  hard  disks.  You 
may  partition  your  hard  disk  into  as  many  drives  as  you  wish;  up  to 
9  can  be  accessed  at  at  time.  By  pressing  one  of  the  buttons  on 
the  Black  Box,  you  will  enter  the  configuration  menu,  where  you 
can  re-assign  drtve  numbers,  etc.  When  you  exit,  you  will  be  right 
back  in  the  program  you  were  running  when  the  switch  was 
pressed  Each  hord  disk  can  be  write-protected.  The  Parallel 
Printer  port  will  allow  you  to  hook  up  any  printer  that  uses  the 
standard  Centronics  interface  As  an  option,  you  can  use  the 
computers  extra  memory  as  a  printer  buffer,  or  order  the  Block 
Box  with  64K  of  on-board  RAM.  You  may  assign  printer  number 
and  line-feed  options  within  the  menu  (for  use  with  multiple 
printers).  Another  omazing  feature  of  the  Black  Box  is  the  built-in 
screen  dump  By  pressing  a  button  (on  the  box),  fhe  contents  of 
your  screen  will  be  dumped  to  your  printer  (you  can  define  text 
or  graphics  modes  with  a  switch)!  The  RS232  port  supplies  the  full 
RS232  spec  signals  tor  connection  to  a  modem,  or  another 
machine  (for  null-modeming).  The  handler  for  the  Black  Box'  s 
modem  port  is  built  in  ar^d  takes  up  NO  memory!  The  port 
handles  rates  up  to  TRUE  19.2K  BAUD!  A  future  upgrade  for  the 
Block  Box  IS  a  floppy  disk  interface  board.  This  will  oilow  the 
addition  of  up  to  four  5,25"  or  5.5"  mixtures  of  floppy  drives  to  be 
used  with  the  system.  The  drives  will  act  like  standard 
single/enhonced/double  density  disk  drives,  but  fvlUCH  faster!  All 
drives  will  be  Super  Archiver  compatible,  and  support  up  to  2 
sides  of  80  tracks.  Along  with  this  hardware  upgrade  will  come 
software  capable  of  reading,  writing,  and  formatting  disks  in  IBM's 
MS-DOS  format  and  the  Atari  ST  format,  and  allow  you  to  transfer 
files  between  those  disk  formats  and  the  Atari  s  format  In 
addition  .  a  machine  language  monitor  has  been  added  to  allow 
memory  disassembly,  memory/register  changes,  and  more  The 
Price  of  the  Block  Box  is  S  199.95  for  the  basic  unit  and  S2'19.95 
with  64K  of  RAM  (for  printer  spooler)  plus  S8  for  S/H/l,  An  optiona' 
custom  BLACK  BOX  case  is  available  for  S39,95  extra, 

$19995       The  "MULTIPLEXER"!©       $19995 

This  device  brings  the  power  and  flexibility  of  larger  systems  to 
your  8-bit.  The  Multiplexer  is  a  device  (actually  a  collection  of 
modules)  that  allow  up  to  8  Atans  to  read  and  write  to  the  same 
drive  (typically  a  hard  disk),  printer,  and  talk  to  each  other    One 

master'  computer  (any  8-bit)  is  eguipped  with  fhe  mosler 
Multiplexer  interface  Then  up  to  8  slave  computers  can  hook  up 
to  the  master,  each  having  their  own  slave  interface     The 

common'  peripherals  (things  that  are  to  be  shared)  are 
connected  to  the  master  computer.  On  each  slave,  all  disk  and 
printer  I/O  is  routed  through  the  master,  so  no  drives  ore  needed 
on  them.  The  master  computer  can  be  configured  in  any  manner 
you  wish  ■  you  can  for  example  have  certain  peripherals  local'  to 
the  slave,  or  routed  to  a  different  number  on  the  master  Under 
development  is  a  BBS  system  that  will  moke  full  use  of  this  device, 
allow  ing  up  to  8  lines/users  to  be  using  the  system  at  the  some 
time!  A  mutiuser  chat  mode  is  a  feature  of  this  program,  however, 
you  do  not  NEED  this  program  to  run  a  BBS  with  the  Multiplexer 
(but  be  warned  thai  not  all  BBS  programs  will  run  concurrently) 
All  slaves  are  independent,  and  do  not  need  to  have  the  same 
program  running  on  them,  This  system  is  excellent  for  BBS  SysOps, 
because  you  con  be' using  your  hiard  disk(s)  while  still  running  your 
BBS  uninterrupted!  Another  example  is  in  a  classroom  situation,  or 
anywhere  o  disk  needs  to  be  shared  by  different  people.  This  is 
on  EXCELLENT  programming/debugging  tool  as  well!  The 
Multiplexer  price  is  S  199.95  tor  a  master  and  two  slave  units  (plus 
55  S/H/l).  Additional  slave  units  are  S69,95  each.

$3995  The  SIO  "POWER  BOOSTER"!®  $3995 

Weak  data  signals  are  often  the  problem  ol  errors  in  data 
transmissions,  especially  when  working  in  High  or  Ultra  Speed 
modes!  Long  cables,  modems,  interfaces,  ond  other  devices 
that  draw  their  power  from  the  computer  rather  than  having 
their  own  power  supply  often  degrade  the  waveform  of  the 
signals  between  your  computer  and  other  peripherals, 
sometimes  resulting  in  errors.  The  SIO  Power  Booster  Coble!  will 
amplify  the  signal  to  and  from  your  computer  20  to  100  times 
providing  perfect  square-wove  data  transmissions  regardless 
of  peripherals  used  ,  The  SIO  Power  Booster"  Coble!  looks  like 
a  standard  SIO  cable  and  simply  plugs  into  your  computer! 
Only  S39,95  plus  S5  S/H/l.

$3995         The  "'QUINTOPUS""!®  $3995 

The  QUINTOPUS'i  is  an  inexpensive  device  mat  provides  a 
tremendous  amount  of  convenience  while  eliminating  the  problems 
associated  with  the  endless  "'daisy-chaining"  of  peripherals  (eg:  drives, 
interfaces,  printers,  modems,  cassettes,  etc.).  The  "QUINTOPUS'"'  is 
an  I/O  port  expander  that  converts  a  single  I'O  outputinput  into  five 
additional  oulpuls  inputs.  Instead  of  datsy-chaining  all  your  peripherals 
{which  often  times  results  in  passing  a  signal  through  30  feet  or  more 
of  cable!),  the  "QUINTOPUS"'  allows  each  device  to  be  connected 
directly  to  Ihe  computers  through  only  three  or  four  feel  ol  cable.  This  is 
particularly  useful  when  attempting  to  use  ULTRASPEED  or 
WARPSPEED  data  transfer  rates.  The  QUINTOPUS  '  also  provides 
the  'extra'  1,0  ports  olten  needed  to  connect  devices  not  having  daisy- 
chaining  capabililies.  Cable  resistance  and  compacitance  are  greally 
reduced  thereby  significantly  improving  the  opportunity  of  accurate 
data  transfers!  Only  $39.95  plus  $5  S  H  i  SIO  cable  is  $5  extra  it 
needed.

This  Deluxe  version  of  the  QUINTOPUS!  has  all  ol  the  above  features

you  can  connect  two  computers  to  one  printer  or  two  printers  lo  one 
computer:  you  can  switch  in  a  computer/printer  combination  and  while 
you're  printing  out  a  long  document,  switch  in  a  second  computer  lo 
access  a  modem,  disk  drive,  cassette  deck,  etc'  Switch  multiple 
combinations  of  peripherals  or  computers  without  the  hassle  or  re-

EDITORIAL 


In  case  you  haven't  already  heard  the  news,  Antic  is  now 
the  last  U.S.  magazine  covering  Atari  XE/XL/800  computers 
exclusively. 

In  order  to  continue  bringing  you  useful  and  entertain- 
ing new  disk  software,  informative  teaching  articles, 
detailed  reviews  and  the  latest  news  about  the  best  8-bit 
personal  computers  ever  made.  Antic  Publishing  was  forced 
to  make  a  tough  decision.  .  . 

Starting  with  the  previous  issue.  Antic  Magazine  became 
a  bi-monthly  publication.  It  will  now  be  published  six  times  yearly,  every  other 
month. 

Of  course,  Antic  subscribers  will  continue  receiving  every  issue  they  paid 
for  The  only  difference  is  that  now  Antic  comes  out  every  second  month. 
At  just  $28  for  a  one-year  subscription  of  six  exclusive  magazines-plus-disk. 
Antic  remains  one  of  the  greatest  bargains  still  available  for  8-bit  Atari  users. 
We  regret  that  it  was  impossible  to  announce  Antic's  switch  to  bi-monthly 
publication  in  the  previous  issue,  when  it  actually  happened.  The  schedule 
changeover  had  to  be  decided  quickly,  while  the  October  1989  issue  was  al- 
ready at  the  printer  There  was  only  enough  time  to  change  the  date  to  Oc- 
tober/November 1989  on  the  front  cover. 

We  have  been  very  heartened  by  the  support  that  Antic  continues  to  receive 
from  thousands  of  committed  8-bit  Atari  users  like  you  (and  a  few  dedicated 
advertisers  too).  Admittedly,  lean  times  have  fallen  on  the  8-bit  Atari  today — as 
well  as  on  all  other  64K-128K  personal  computers.  Still,  there's  a  core  group 
of  Atari  enthusiasts  who  keep  spending  their  money  to  continue  getting  the 
useful  information  and  high-quality  original  software  that  Antic  has  provided 
for  Atarians  non-stop  since  1982. 

At  this  point.  Antic  has  become  a  reader-supported  magazine.  (We're  cer- 
tainly not  supported  by  advertising,  backed  by  a  big  publishing  conglomerate, 
or  subsidized  by  Atari.)  We  actually  consider  ourselves  to  be  in  a  partnership 
with  our  readers.  Like  us,  your  goal  is  to  keep  your  Atari  8-bit  as  a  workable 
computing  tool  for  many  more  years.  Together,  Antic  and  you  c;in  do  it.

Back  in  1977,  Nolan  Bushnell  of  Atari  put 
Dorsett  Educational  Systems,  Inc.  under 
contract  to  produce  at  least  256  "half- 
hour"  interactive  audiovisual  programs. 
We  eventually  produced  832  program  ti- 
tles. At  one  point,  our  "Talk  and  Teach" 
programs  were  offered  through  dealers 
and  in  the  J.C.  Penney  catalog.  Atari  sold 
the  rights  back  to  Dorsett  in  1981,  and  we 
have  been  selling  them  and  newer  titles 
ever  since. 

The  programs  come  in  series  of  16,  two 
to  a  cassette.  These  programs  require  the 
use  of  a  cassette  recorder,  but  we  find  that 
the  Atari  410  and  1010  recorders  are  avail- 
able through  Antic  mail-order  advertisers. 
Dorsett 's  S25  Educational  System  Master 
Cartridge  is  also  required.  Each  16- 
program  course  is  85990. 

Programs  still  available  include  254  half- 
hour  reading  comprehension  and  de- 
velopment programs,  U.S.  and  World  His- 
tory and  Government,  160  math  programs 
(including  our  best-selling  Algebra  course), 
Physics,  Statistics,  Electronics,  96  voca- 
tional programs,  and  even  Arniy  Skills  and 
Philosophy.  Free  catalogs  will  be  sent  to 
the  first  200  requests.

BIKER  DAVE  BUMMER 

Biker  Dave  Atari,  the  Super  Disk  Bonus 
in  the  September  1989  Antic  under  Erik 
Lowell's  byline,  actually  was  written  by 
David  Schwener  and  published  in  the 
November  1986  issue  of  COMPUTE! 
magazine.  The  two  listings  match  exactly, 
except  for  authorship  and  magazine 
credits. 

Perhaps  Erik  Lowell  figured  no  one 
would  remember  or  know  where  the  pro- 
gram was  originally  published,  since  three 
years  have  elapsed  since  publication.  Your 


article  said  that  Lowell  is  a  14-year-old 
from  Massachusetts  "who  is  very  in- 
terested in  becoming  a  professional  soft- 
ware developer"  It  saddens  me  to  think 
that  a  young  person  would  choose  to  ob- 
tain his  first  professional  programming 
credit  in  such  a  callous  way.  I  imagine  his 
career  will  be  very  short  if  this  trend  con- 
tinues. 

Also,  when  Biker  Dave  was  published 
in  COMPUTE!  it  would  not  run  on  my 
800.  The  display  would  jump  and  roll  as 
soon  as  the  play  screen  came  up.  The  same 
problem  occurs  with  the  program  on  the 
Antic  Monthly  Disk.  The  fix  is  simple.  Just 
make  the  following  change; 

2910  NEXT  LPOKEDL 4-22,65 

Darryl  Howerton 
Jonesboro,  AR 

Even  the  Display  List  error  from  the 
original  Biker  Dave  is  in  your  Super  Disk 
Bonus.  1  fixed  this  problem  for  my  own 
system  back  in  1986  by  adding  these  lines: 

2912  POKE  DL  + 22,65 

2913  POKE  DL  +  23,32 

2914  POKE  DL  +  24,152 

The  game  will  run  as  is  on  some  moni- 
tors or  TV  sets  if  you  adjust  the  line  fre- 
quency, but  I  had  to  correct  the  program 
for  my  monitor 

Doug  Scott 
Santa  Clara,  CA 

Another  note  about  the  original  Biker 
Dave  is  that  the  program  will  not  work 
if  you  [BREAK]  out  of  it  and  try  to  RUN 
it  again.  You  should  reboot  your  system 
and  RUN  the  program  again. 
Mark  Miller 
Boulder,  CO 

Many  alert  readers  wrote  or  called 
right  away  to  let  us  know  about  the  prob- 
lem of  Biker  Dave  authorship — including 
longtime  Antic  contributor  David 
Plotkin. 

Antic  sincerely  apologizes  to  COM- 
PUTE! Magazine  and  to  the  rightful  au- 
thor of  Biker  Ovkc  for  having  mistakenly 
reprinted  their  program.  We  would  like 
to  locate  David  Schwener  so  we  can  pay 
him  the  fee  that  Lowell  was  supposed  to 
get. 


Lowell  has  written  to  Antic  that  he  pro- 
grammed his  otvn  unique  adaptation  of- 
Biker  Dave.  I-!e  enclosed  an  unreadable 
disk  which  was  supposed  to  contain  this 
new  version.  Lowell  claims  he  just  made 
a  'clerical  error'  by  mistakenly  submit- 
ting a  disk  file  of  Schwener 's  original 
game.  However,  Lx>well's  submission  to 
Antic  also  included  a  printout  of 
Schwener 's  program — with  Lowell 
named  as  author 

We  are  grateful  to  all  the  Antic  readers 
who  spotted  this  unfortunate  situation, 
including  at  deadline:  fohn  Andrews, 
Keith  Brock,  Fred  Dormagen,  Rodolfo 
Pong,  Bruce  LLathaway,  Sylvia  fumaga, 
fohn  Kelts,  fohn  Lcmgham,  Phyllis  Mar- 
garitas, Bruce  Smith  and  Robert  von 
Frisch. 

The  screen  Flipping  problem  men- 
tioned by  sevei'al  readers  doesn  't  seem  to 
happen  on  the  monitors  Antic  uses,  so 
we  are  passing  along  their  suggested  fixes 
without  being  able  to  check  them  fully.—

ATARIWRITER  HELP 

In  your  July,  1989  I/O  column,  you  told 
a  reader  to  try  using  the  Printer  Driver 
Construction  Set  to  solve  his  problems 
with  AtariWriter  subscripts  on  his  Epson 
LX-80  printer  Unfortunately,  the  Printer 
Driver  Construction  Set  was  written  be- 
fore the  LX-80  came  out,  and  probably 
wouldn't  solve  the  problem. 

The  best  answer  to  this  problem  is  to 
type: 

[CONTROL-O]27S0o[CONTROL- 
0]27T 

The  [CONTROL-O]  signifies  one  char- 
acter made  by  pressing  the  [CONTROL] 
and  [O]  keys  simultaneously.  This  charac- 
ter gives  control  from  AtariWriter  to  the 
printer.  27  is  the  ESCAPE  decimal  code  for 
the  LX-80  printer,  SO  turns  on  the  super- 
script (SI  turns  on  subscript).  The  "o"  was 
my  superscript  degree  character — you 
would  put  your  own  superscript  or  sub- 
script character  here.  Then  the 
[CONTROL-O]  accesses  the  printer  again, 
and  the  27T  tells  the  printer  to  return  to 
regular  line  spacing.

I/O  BOARD 


Of  course,  another  solution  would  be 
to  buy  AtariWriter  Plus,  which  has  a  Cus- 
tom Printer  Driver,  and  a  lot  more.  Com- 
bined with  the  Epson  manual,  and  a  bit 
of  trial  :ind  error,  this  will  help  much  more 
than  an  outdated  printer  driver  program.

AMPLE  CONFUSION 

Back  in  your  June  1989  issue,  you  talk 
about  Antic  Music  Processor  "Scott  Joplin" 
music.  Did  I  miss  it,  or  didn't  you  put  it 
on  the  disk? 

Fred  Portelli 

Ocala,  FL 

On  the  June,  1989  disk,  the  AMP  files  are: 
CASCADES,  AUGUST,  PRE20.JSB, 
SPRING,  RHAP4,  ROUND3,  DYER- 
MAKE,  FIRST2,  PICTURES4,  MAJOR- 
GEN,  CHEERS.AMP  FELON.  On  subse- 
quent disks  we  made  song  files  easier  to 
identify  by  ending  them  all  with  .AMP. 
'  Rather  than  use  the  over-familiar  En- 
tertainer, we  put  two  lesser-known  Joplin 
tunes  on  the  disk,  the  Augustan  Club 
Waltz  (AUGUST)  and  The  Cascades.  An- 
other Joplin  tune.  Easy  Winners 
(EASY.AMP)  made  it  onto  thejtdy  1989 
disk,  along  with  a  rag  a  boogie,  and  two 
other  tunes.  The  August  1989  disk  in- 
cludes a  minor  upgrade  to  AMP  (version 
2. 1)  and  three  contemporary  songs.

By  Jeffrey  Summers,  MD 


see  why  a  violin  sounds 
different  from  a  clarinet. 


Sound  waves  move  in  strange  and  mys- 
terious ways.  If  you  ever  ^wondered 
what  makes  a  violin  sound  different 
from  a  clarinet,  Antic  Sound  Creator 
^will  help  you  explore  the  wonders  of 
harmonics.  This  simple,  easy-to-use  BA- 
SIC program  works  on  8-bit  Atari  com- 
puters with  at  least  48K  memory  and 
disk  drive. 


Sitting  pn  a  park  lawn  listen- 
ing to  a  band  playing  a  free 
concert  on  a  warm  spring- 
time day,  I  started  thinking 
about  what  makes  different  instru- 
ments sound  different.  A  trumpet  and 
a  flute,  for  example,  may  play  the 
same  note,  yet  they  sound  different. 
The  differences  in  sound  character 
that  distinguish  one  instrument  from 

DECEMBER  1989/JANlIARY  1990 


another  are  due  to  the  presence  of 
"harmonics"  or  overtones.  To  under- 
stand what  these  are  and  why  they  are 
important,  think  of  a  jumprope.  It  is 
easy  to  make  a  jumprope  move  up 
and  down  along  its  entire  length.  This 
we  will  call  the  primary  wave. 

With  a  little  more  energy  and  a  flick 
of  the  wrist,  it  is  possible  for  you  to 
get    the    rope    to    vibrate    in    two 


halves — when  one  half  of  the  rope  is 
up,  the  other  half  is  down,  and  vice 
versa.  The  center  of  the  rope  doesn't 
move  in  this  situation.  This  we  will 
call  the  secondary  wave.  If  you  are 
Hulk  Hogan  you  can  probably  get  the 
rope  to  further  split  into  thirds  or 
quarters,  but  it  gets  a  lot  more  dif- 
ficult. 

Anyway,  if  you  think  of  the  primary 
wave  as  your  first  harmonic,  then  the 
secondary  wave  as  the  second  har- 
monic and  so  on,  you  get  the  idea  of 
what  a  harmonic  is.  When  a  violin 
string  vibrates,  the  primary  wave  is 
produced  by  the  entire  length  of 
string  vibrating. 

However,  to  a  lesser  extent  the 
string  also  vibrates  in  halves,  thirds, 
quarters,  and  so  on.  If  you  look 
closely  at  a  vibrating  violin  string  you 
can  actually  see  points  on  the  string 
where  the  vibrations  decrease.  (The 
harmonic  point  in  the  center  of  the 
string  is  usually  the  easiest  to  spot.) 
It  is  the  relative  contribution  of  these 
overtones  that  make  the  violin  sound 
like  a  violin.  A  flute,  playing  the  same 
note,    will    have    different    relative 


amounts  of  the  overtones  or  har- 
monics and  therefore  it  sounds  differ- 
ent from  the  violin. 

GEniNG  STARTED 

To  demonstrate  this  concept  I 
wrote  the  Antic  Sound  Creator.  This 
program  allows  you  to  create  a  sound 
wave  either  by  drawing  the  wave  free- 
hand, or  by  adding  overtones  to- 
gether, or  by  combining  both 
methods.  To  use  the  program,  type  in 
Listing  1,  check  it  with  Typo  II  and 
be  sure  to  SAVE  a  copy  before  you 
RUN  it. 

When  the  program  starts,  an  x-axis 
and  a  y-axis  are  drawn  in  orange. 
Then  a  flat  wave  is  drawn  in  green. 
The  wave  is  flat  because  we  haven't 
designed  anything  yet.  A  menu  ap- 
pears at  the  bottom  of  the  screen.  The 
options  are  to  Add  a  Harmonic,  Load 
and  Save  waves,  Clear  the  wave. 
Quantize,  Play,  Draw,  and  Exit. 

MAKING  WAVES 

Adding  a  harmonic  will  add  a  sine 
wave  to  the  current  wave.  You  are  first 
asked  which  harmonic  you  wish  ad- 
ded. A  pure  sine  wave  whose  length 
would  fill  the  pattern  would  be  har- 
monic number  1.  A  sine  wave  that 
would  repeat  once  across  the  screen 
(two  sine  waves)  would  be  2,  and  so 
on.  For  our  example,  enter  1. 

You  are  next  asked  for  a  scaling  fac- 
tor. This  will  govern  the  amplitude 
(loudness)  of  the  wave  being  added. 
The  value  of  the  scaling  factor  can 
range  from  zero  to  a  maximum  of  1. 
Values  above  1  will  be  cut  off.  It  is  dif- 
ficult to  add  large-scaled  harmonics 
together  without  such  "clipping" 
(more  on  this  later).  For  our  example, 
enter  .3. 

The  new  wave  is  now  drawn  on  the 
screen.  To  hear  what  this  pure  sine 
wave  sounds  like,  press  [P]  to  play  the 
wave.  You  are  then  asked  for  a  delay 
factor  from  1  to  10.  The  number  you 
enter  will  regulate  the  pitch  of  the 
tone.  The  values  from  1  to  10  and 
their  approximate  pitches  (very  ap- 
proximate in  some  cases)  are  shown 


in  Figure  1.  For  Our  example,  enter  3 
for  the  delay.  After  a  moment,  the 
screen  clears  and  you  will  hear  the 
sound  through  your  speaker. 

Press  any  key  to  stop  the  sound  and 
return  to  your  screen.  Next  let's  add 
an  overtone.  Type  [A]  to  add  another 
harmonic,  and  when  you  are  asked 
which  harmonic  you  wish  to  add. 


Antic  Sound  Creator 

type  2.  For  the  scale,  enter  .3  again. 
The  second  wave  is  added  to  the  first 
mathematically,  and  the  resulting 
combined  wave  will  be  drawn.  Press 
[P]  to  hear  the  new  wave.  See  and  hear 
the  difference?  Not  much,  with  only 
one  harmonic  added,  but  you'll  see 
more  changes  later,

DRAWING  WAVES 

Now  let's  draw  in  a  few  changes  to 
our  wave.  When  you  press  [D],  a  cur- 
sor appears  toward  the  bottom  of  the 
screen.  The  cursor  is  under  the 
column  you  are  working  on.  You  may 
use  the  joystick  or  the  [ARROW  KEYS] 
(holding  the  [CONTROL]  key  is  not 
necessary)  to  move  the  cursor  side- 
ways from  column  to  column  and 
up/down  to  change  values.  To  exit  the 


Draw  mode,  simply  move  the  cursor 
all  the  way  to  the  right,  off  the  wave. 

Using  Draw  mode,  you  can  change 
the  shape  of  the  wave  as  you  wish  and 
hear  the  results.  You  can  draw  waves 
that  would  be  nearly  impossible  to 
create  from  the  addition  of  overtones, 
such  as  square  waves  and  sawtooth 
patterns.  To  exit  the  draw  mode  sim- 
ply move  the  cursor  off  the  wave  to 
the  right. 

The  POKEY  chip,  which  actuaUy 
produces  the  sound  we  hear,  only  al- 
lows sixteen  different  values  on  the 
vertical  y-axis  of  our  graph.  To  get  the 
most  accuracy  possible,  the  values  for 
the  wave  are  stored  in  the  usual  Atari 
floating  point  format.  But  when  PO- 
KEY actually  plays  the  wave  it  must 
be  scaled  to  the  range  0-15.  Thus,  if 
you  make  a  very  minor  change  to  the 
wave  on  the  screen,  it  may  make  no 
change  at  all  to  what  you  hear  due  to 
the  limitations  imposed  by  POKEY. 

To  see  exactly  what  POKEY  will 
play,  you  may  press  [Q]  to  quantize 
the  wave.  This  converts  the  current 
wave  into  the  actual  wave  POKEY  will 
play.  It  usually  isn't  as  pretty,  and  you 
can't  un-quantize  back  to  your  origi- 
nal wave.  So  make  sure  you  save  your 
wave  before  you  quantize,  if  you  think 
you  want  to  keep  it  and  later  modify 
it. 

Pressing  [S]  allows  you  to  save  the 
wave  you  have  been  working  on.  You 
are  prompted  for  a  filename.  If  you 
don't  enter  a  device,  D:  is  assumed. 
The  program  will  then  save  your  data. 
Later,  you  may  re-enter  your  data  by 
using  the  [L]  command  and  entering 
the  same  filename.     |      ' 

For  the  technicaUy-minded  who 
wish  to  create  sounds  not  easily 
created  by  the  addition  on  harmonics 
nor  by  freehand  drawing,  it  would  be 
easy  to  create  a  file  compatible  with 
this  program.  The  files  simply  consist 
of  a  list  of  100  numbers  ranging  from 
zero  to  sixteen,  separated  by 
[RETURN]s. 

Thus,  you  can  write  a  quick  pro- 
gram to  generate  the  file  so  you  can 
graph    and   play   such    waves    as

CLIPPING  PENALTIES 

What  happens  when  you  add  too 
many  harmonics  together  and  exceed 
the  legal  range  of  values  of  the 
program? 

To  see,  use  [C]  to  clear  the  current 
wave.  Now  press  [A]  to  add  a  har- 
monic, enter  a  1  for  the  harmonic, 
then  enter  .4.  Play  this  with  a  delay 
of  5 .  The  sound  should  be  a  nice  pure 
sine  wave. 

Clear  again  and  create  a  first  har- 
monic wave  with  a  scale  of  .8.  Play 
this  and  aside  from  an  increase  in 
loudness  the  sound  should  be  the 
same.  Clear  again  and  create  a  first 
harmonic  wave  with  a  scale  of  1.5- 
Look  at  the  wave  on  the  screen.  See 
how  it  looks  clipped  off  on  the  top 
and  bottom? 

Now  play  this  also  with  a  delay  of 
5.  The  difference  you  hear  is  due  to 
"clipping".  Now  when  you  buy  ste- 


reo equipment  you  will  know  what 
the  salesman  means  when  he  talks 
about  speakers  clipping  when  a  cer- 
tain volume  is  reached.  Pressing  [E] 
clears  the  screen  and  exits  the 
program. 


You  can  change 
the  shape  of  the 

^vave  as  you 

wish  and  hear 

the  results. 


INSTRUMENTAL  MIMICRY 

Now  that  you  know  how  the  pro- 
gram works,  let's  try  some  different 


sounds.  If  you  have  a  wave  on  the 
screen,  press  [C]  to  clear  it.  Press  [A] 
to  add  a  harmonic,  and  use  the  first 
harmonic  with  a  scaling  of  .3-  Next 
add  harmonic  number  2  with  the 
same  scaling  of  .3.  Continue  adding 
harmonics  with  values  of  4, 8,  and  16, 
all  with  scalings  of  .3- 

Now  play  the  wave.  It  sounds  to  me 
like  an  organ.  Save  this  if  you  like, 
then  use  [C]  to  clear  the  wave.  Now, 
add  harmonics  with  values  of  1,  3,  5, 
7,  and  9  all  with  scaling  values  of  .3. 

Play  this,  also  with  a  delay  of  5  ■  It 
may  not  be  Benny  Goodman,  but  to 
me  it  sounds  like  a  clarinet.  A

puters with  at|^ast  48K  memory  and 
disk  drive.  An  Epson-compatible  printer 
is  optional. 


In  physics  and  other  sciences, 
the  term  "chaos"  has  come  to 
mean  the  study  of  determinis- 
tic disorder  This  is  a  relatively 
new  field  that  integrates  many  sub- 
disciplines  of  mathematics  and  the 
sciences.  Chaos  covers  the  study  of 
fragmented   and   irregular   fractal 


shapes  such  as  clouds,  mountains, 
coastlines,  and  tree  bark,  which  all  ex- 
hibit increasing  detail  when  mag- 
nified. 

In  addition,  chaos  involves  the 
study  of  non-linear  dynamic  systems 
exhibiting  unpredictable  and  random 
behavior.  Studies  of  biological  popu- 


lations, climate  processes,  economic 
fluctuations  and  the  dynamics  of 
Jupiter's  Great  Red  Spot  are  all  co- 
vered in  the  same  discipline  as  studies 
of  fractal  shapes. 

The  word  fractal  was  coined  in 
1975  by  the  mathematician  Benoit 
Mandelbrot  to  describe  his  shapes, 
dimensions  and  geometry.  The  word 
itself  is  a  contraction  of  "fractional 
dimensions,"  but  most  people  think 
of  fractals  simply  as  shapes  that  are 
self-similar 

A  coastline,  for  example,  has  a 
highly  irregular  fractal  shape.  As  its 
structure  is  magnified,  more  of  its  ir- 
regularity is  revealed,  but  the  sort  of 
shapes  formed  by  the  coastline  re- 
main the  same,  whether  you  are  look- 
ing close  up  at  a  small  inlet  or  from 
a  satellite  at  a  major  bay. 

In  studying  fractal  shapes,  a  num- 
ber of  patterns  have  been  identified. 
The  Mandelbrot  set,  Koch  curves  and 
Sierpinski  gaskets  are  some  well- 
known  examples  of  fractal  shapes.

ANTIC,  THE  ATARI  RESOURCE 


cle  in  the  April  1986  Antic  for  more 
on  fractals  and  the  Mandelbrot  set, 
also  known  as  the  Julia  curve.)  All 
these  shapes  result  from  determinis- 
tic processes. 

To  make  a  Koch  snowflake  curve, 
begin  with  an  equilateral  triangle.  At 
the  middle  of  each  side,  add  a  smaller 
triangle  one-third  the  size  of  tfie  origi- 
nal triangle.  This  results  in  a  six- 
pointed  figure.  At  the  middle  of  each 
side  of  this  figure  add  still  smaller  tri- 
angles, and  so  on. 

To  make  a  Sierpinski  gasket,  start 
with  another  equilateral  triangle.  Di- 
vide the  triangle  into  four  smaller  tri- 
angles by  drawing  lines  from  the  mid- 
dle of  each  side  to  the  other  two  sides. 
Remove  the  central  triangle.  Repeat 
the  process  with  the  remaining  three 
triangles  and  remove  the  central  tri- 
angle from  each  of  them.  Nine  stiU 
smaller  triangles  remain.  The  process 
continues  infinitely  in  the  fractal,  even 
if  it  becomes  impossible  to  actually 
draw  the  ever  smaller  triangles  with 
ordinary  pencil  and  paper — or  com- 
puter screen. 

Rather  than  generate  fractal  shapes 
from  such  deterministic  processes  as 
just  described,  Michael  Bamesley  of 
the  Georgia  Institute  of  Technology 
takes  a  different  approach.  He  con- 
structs fractals  through  a  random 
process  he  calls  the  Chaos  Game.

the  vertices  (points)  of  a  triai^le  arc 
located  at  the  screen  coordinates 
(0,0),  (318,0)  and  (159,191).  These  ver- 
tices are  respectively  designated  as  1, 
2  and  3. 

First  the  computer  randondy  picks 
a  poiru  anywhere  on  the  screen.  Nesa, 
one  of  the  vertices  is  rantkMnly  cho- 
sen. A  point  is  then  plotted  (dnmii) 
halfway  between  the  initial  poim  and 
this  vertex.  From  this  point  a  second 
pKjint  is  plotted  halfway  to  the  next 
randomly  chosen  vertex.  The  pnxxss 
is  repe^ed  over  and  oven 

At  first,  the  process  appears  to  ran- 
domly place  dots  all  over  the  scteen. 
However;  after  a  short  period  of  time 
the  pattern  of  the  Sierpinski  gasket  be- 
gins to  emerge.  It  is  fascinating  to 
watch  order  appear  from  chaos.    ; 

Instead  of  dividing  the  distanclfi

Mapping  the 


Atari 


Exclusive! 


Classic  8-bit  reference  book  returns. 

By  Ian  Chadwick 


Antic  continues  the  exclusive  serializa- 
tion of  key  excerpts  from  the  revised 
second  edition  of  Ian  Chadwick's  "Map- 
ping the  Atari."  Virtually  impossible  to 
obtain  today,  this  book  has  been  one  of 
the  key  reference  sources  for  intermedi- 
ate and  advanced  Atari  8-bit  program- 
mers since  1983. 

This  exclusive  Antic  serialization  be- 
gan in  the  August  1989  issue,  with  an 
explanation  of  how  to  use  the  memory 
map  locations  presented  in  each  succes- 
sive issue. 


Locations  512  to  1151  (S200  to 
$47F)  are  used  by  the  OS  for  work- 
ing variables,  tables  and  data  buffers. 
In  this  area,  locations  512  to  553 
(S200  to  S229)  are  used  for  interrupt 
vectors,  and  locations  554  to  623 
(S22A  to  Jf26F)  are  for  miscellaneous

use.  Much  of  pages  two  through  five 
cannot  be  used  except  by  the  OS  un- 
less specifically  noted.  A  number  of 
bytes  are  marked  as  'spare',  i.e.,  not  in 
use  currently.  The  status  of  these  bytes 
may  change  with  an  Atari  upgrade,  so 
their  use  is  not  recommended. 


There  are  two  types  of  interrupts: 
Non-Maskable  Interrupts  (NMI) 
processed  by  the  ANTIC  chip  and  In- 
terrupt Requests  (IRQ)  processed  by 
the  POKEY  and  the  PIA  chips.  NMI's 
are  for  the  VBLANK  interrupts  (VBI's; 
546  to  549,  S222  to  S225),  display  list 
interrupts  (DLI)  and  RESET  key  inter- 
rupts. They  initiate  the  stage  one  and 
stage  two  VBLANK  procedures; 
usually  vectored  through  an  OS  serv- 
ice routine,  they  can  be  vectored  to 
point  to  a  user  routine.  IRQ's  are  for 
the  timer  interrupts,  peripheral  and 
serial  bus  interrupts,  BREAK  and 
other  key  interrupts,  and  6502  BRK 
instruction  interrupts.  They  can 
usually  be  used  to  vector  to  user  rou- 
tines. See  NMIST  54287  (SD40F)  and 
IRQEN  53774  ($D20E)  for  more  in- 
formation. NMI  interrupt  vectors  are 
marked  NMI;  IRQ  interrupt  vectors 
are  marked  IRQ.

VDSLST 


The  vector  for  NMI  Display  List  In- 
terrupts (DLI):  containing  the  address 
of  the  instructions  to  be  executed  dur- 
ing a  DLI  (DLI's  are  used  to  interrupt 
the  processor  flow  for  a  few  microse- 
conds at  the  particular  screen  display 
line  where  the  bit  was  set,  allowing 
you  to  do  another  short  routine  such 


17 


as  music,  changing  graphics  modes, 
etc.).  The  OS  doesn't  use  DLI's;  they 
must  be  user-enabled,  written  and 
vectored  through  here.  The  NMI  sta- 
tus register  at  54287  ($D40F)  firet  tests 
to  see  if  an  interrupt  was  caused  by 
a  DLI  and,  if  so,  jumps  through 
VDSLST  to  the  routine  written  by  the 
user  DLI's  are  disabled  on  powerup, 
but  VBI's  are  enabled  (see  546  to  549; 
$222  to  S225). 

VDSLST  is  initialized  to  point  to 
59315  (SE7B3),  which  is  merely  an 
RTI  instruction.  To  enable  DLI's,  you 
must  first  POKE  54286  ($D40E)  with 
192  (SCO);  otherwise,  ANTIC  will  ig- 
nore your  request.  You  then  POKE 
512  and  513  with  the  address 
(LSB/MSB)  of  the  first  assembly  lan- 
guage routine  to  execute  during  the 
DLI.  You  must  then  set  BIT  7  of  the 
Display  List  instruction(s)  where  the 
DLI  is  to  occur.  You  have  only  be- 
tween 14  and  6l  machine  cycles  avail- 
able for  your  DLI,  depending  on  your 
GRAPHICS  mode.  You  must  first  push 
any  6502  registers  onto  the  stack,  and 
you  must  end  your  DLI  with  an  RTI 
instruction.  Because  you  are  dealing 
with  machine  language  for  your  DLI, 
you  can  POKE  directly  into  the  hard- 
ware registers  you  plan  to  change. 


514,515 


202,203 


Serial  (peripheral)  proceed  line  vec- 
tor, initialized  to  59314  ($E7B2), 
which  is  merely  a  PLA,  RTI  instruc- 
tion sequence.  It  is  used  when  an  IRQ 
interrupt  occurs  due  to  the  serial  I/O 
bus  proceed  line  which  is  available  for 
peripheral  use. 


516,517 


204,205 


VINTER

initialized  to  59314  ($E7B2).  Used  for 
the  IRQ  interrupt  due  to  a  serial  bus 
I/O  interrupt. 


518,519 


206,207         VBREAK 


(not  the  BREAK  key,  which  is  at  loca- 
tion 17;  Sll),  initialized  to  59314 
(SE7B2).  This  vector  is  normally  used 
for  setting  break  points  in  an  assem- 
bly language  debug  operation.  IRQ. 


520,521 


208,209         VKEYBD 


POKEY  keyboard  interrupt  vector, 
used  for  an  interrupt  generated  when 
any  keyboard  key  is  pressed  other 
than  BREAK  or  the  console  buttons. 
Console  buttons  never  generate  an  in- 
terrupt unless  one  is  specifically  user- 
written.  VKEYBD  can  be  used  to 
process  the  key  code  before  it  under- 
goes conversion  to  AT\SCI1  form.  In- 
itialized to  65470  (SFFBE),  which  is 
the  OS  keyboard  IRQ  routine. 

522,523  20A,20B  VSERIN 

POKEY  serial  I/O  bus  receive  data 
ready  interrupt  vector,  initialized  to 
60177  ($EB11),  which  is  the  OS  code 
to  place  a  byte  from  the  serial  input 
port  into  a  buffer  CaUed  INTRVEC  by 
DOS,  it  is  used  as  an  interrupt  vector 
location  for  an  SIO  patch,  DOS 
changes  this  vector  to  6691  (S1A23), 
the  start  of  the  DOS  interrupt  ready 
service  routine.  IRQ.

Software  break  instruction  vector 
for  the  6502  BRK  (100)  command 


POKEY  serial  I/O  transmit  ready 
interrupt  vector,  initialized  to  60048 
(EA90),  which  is  the  OS  code  to  pro- 
vide the  next  byte  in  a  buffer  to  the 
serial  output  port.  DOS  changes  this 
vector  to  6630  (S19E6),  the  start  of  the 
DOS  output  needed  interrupt  routine. 
IRQ. 

526,527  20E,20F  VSEROC 

POKEY  serial  bus  transmit  com- 
plete interrupt  vector,  initialized  to 
60113  (SEADl),  which  sets  a  transmis- 
sion done  flag  after  the  checksum 
byte  is  sent.  IRQ. 

528,529  210,211  VTIMRl 

POKEY  timer  one  interrupt  vector. 


initialized  to  59314  ($E7B2),  which  is 
a  PLA,  RTI  instruction  sequence. 
Timer  interrupts  are  established  when 
the  POKEY  timer  AUDFl  (53760; 
!SD200)  counts  down  to  zero.  Values 
in  the  AUDF  registers  are  loaded  into 
STIMER  at  53769  (SD209).  IRQ. 


530,531 


212,213  VTIMR2 


POKEY  timer  two  vector  for 
AUDF2  (53762,  $D202),  initialized  to 
59314  (»E7B2).  IRQ. 

532,533  214,215  VTIMR4 

POKEY  timer  four  vector  for 
AUDF4  (53766,  SD206),  initialized  to 
59314  (SE7B2).  This  IRQ  is  only  vec- 
tored in  the  'B'  version  of  the  OS 
ROMs. 

534,535  216,217  VIMIRQ 

The  IRQ  immediate  vector 
(general).  Initialized  to  59126  ($E6F6). 
JMP  through  here  to  determine  cause 
of  the  IRQ  interrupt.  Note  that  with 
the  new  ('B')  OS  ROMs,  there  is  a 
BREAK  key  interrupt  vector  at  loca- 
tions 566,567  ($236,  S237). 

The  locations  from  536  to  558 
($218  to  $22E)  are  used  for  the  sys- 
tem software  timers.  Hardware  timers 
are  located  in  the  POKEY  chip  and 
use  the  AUDF  registers.  These  timers 
count  backwards  every  1  /60  second 
(stage  one  VBLANK)  or  1  /  30  second 
(stage  two  VBLANK)  interval  until 
they  reach  zero.  If  the  VBLANK  proc- 
ess is  disabled  or  intercepted,  the 
timers  will  not  be  updated.  These  lo- 
cations are  user-accessible  and  can  be 
made  to  count  time  for  music  dura- 
tion, game  I/O, game  clock  and  other 
functions. 

Software  timers  are  used  for  dura- 
tions grater  than  one  VBLANK  inter- 
val (I/60  second).  For  periods  of 
shorter  duration,  use  the  hardware 
registers.

ANTIC,  THE  ATARI  RESOURCE 


System  timer  one  value.  Counts 
backwards  from  255-  This  SIO  timer 
is  decremented  every  stage  one 
VBLANK.  When  it  reaches  zero,  it  sets 
a  flag  to  jump  QSR)  through  the  ad- 
dress stored  in  locations  550,551 
($226,  S227).  Only  the  realtime  clock 
(locations  18-20;  S 12-14),  timer  one, 
and  the  attract  mode  register  (77; 
$4D)  are  updated  when  the  VBLANK 
routine  is  cut  short  because  time- 
critical  code  (location  66;  $42  set  to 
non-zero  for  critical  code)  is  executed 
by  the  OS. 


538,539 


21A,21B         CDTMV2 


System  timer  two.  Decremented  at 
the  stage  two  VBLANK.  Can  be 
decremented  every  stage  one 
VBLANK,  subject  to  critical  section 
test  as  defined  by  setting  of  CRITIC 
flag  (location  66;  $42).  This  timer  may 
miss  (skip)  a  count  when  time-critical 
code  (CRITIC  equals  non-zero)  is  be- 
ing executed.  It  performs  a  JSR 
through  location  552,  553  ($228, 
$229)  when  the  value  counts  down 
to  zero. 

540,541  21C,21D        CDTMV3 

System  timer  three.  Same  as  538. 
Timers  three,  four,  and  five  are 
stopped  when  the  OS  sets  the  CRITIC 
flag  to  non-zero  as  well.  The  OS  uses 
timer  three  to  OPEN  the  cassette 
recorder  and  to  set  the  length  of  time 
to  read  and  write  tape  headers.

'B'  ROMs;  59310,  $E7AE).  The  NMI 
status  register  tests  to  see  if  the  inter- 
rupt was  due  to  a  VBl  (after  testing  for 
a  DLI)  and,  if  so,  vectors  through  here

by  the  IRQ  device  routine.  It  estab- 


lishes the  initial  1 12  second  delay  be- 
fore a  key  will  repeat.  Stage  two

SDMCTL 


Direct  Memory  Access  (DMA)  ena- 
ble. POKEing  with  zero  allows  you  to 
turn  off  ANTIC  and  speed  up  process- 
ing by  30  % .  Of  course,  it  also  means 
the  screen  goes  blank  when  ANTIC 
is  turned  off!  This  is  useful  to  speed 
things  up  when  you  are  doing  a  cal- 
culation that  would  take  a  long  time. 
It  is  also  hat^dy  to  turn  off  the  screen 
when  loading  a  drawing,  then  turn- 
ing it  on  when  the  screen  is  loaded 
so  that  it  appears  instantly,  complete 
on  the  screen.  To  use  it  you  must  first 
PEEK  (559)  and  save  the  result  in  or- 
der to  return  your  screen  to  you.  Then 
POKE  559,0  to  turn  off  ANTIC.  When 
you  are  ready  to  bring  the  screen  back 
to  life,  POKE  559  with  the  number 
saved  earlier 


560,561 


230,231 


SDLSTL 


Starting  address  of  the  display  list. 
The  display  List  is  an  instruction  set 
to  tell  ANTIC  where  the  screen  data 
is  and  how  to  display  it.  These  loca- 
tions are  the  shadow  for  54274  and 
54275  ($D402,  $D403).

the  SIO  bus  ID  number.  The  other 
three  CFB  bytes  are: 

571  23B  CCOMND 
The  SIO  bus  command  code. 

572  23c  CAUXl 

Command  auxiliary  byte  one,

read  from  the  first  disk  record. 

578,579  242,243        BOOTAD 

The  address  for  where  the  disk 
boot  loader  will  be  put.  The  record 
just  read  will  be  moved  to  the  address 
specified  here,  followed  by  the  re- 
maining records  to  be  read.  Normally, 
with  DOS,  this  address  is  1792  (S700), 
the  value  also  stored  temporarily  in 
RAMLO  at  4,5.  Address  62189 
($F2ED)  is  the  OS  disk  boot  routine 
entry  point  (DOBOOT). 


580 


244  COLDST 


Coldstart  flag.  Zero  is  normal;  if 
zero,  then  pressing  RESET  will  not  re-

puter will  reboot  whenever  the 
RESET  key  is  pressed. 


582 


246 


DSKTIM 


Disk  time-out  register  (the  address 
of  the  OS  worst  case  disk  time-out). 
It  is  said  by  many  sources  to  be  set  to 
160  at  initialization,  which  represents 
a  171  second  time-out,  but  my  system 
shows  a  value  of  224  on  initialization. 
Timer  values  are  64  seconds  for  each 
60  units  of  measurement  expressed. 

583-622  247-26E  LINBUF 

Forty-byte  character  line  buffer, 
used  to  temporarily  buffer  one  phys- 
ical line  of  text  when  the  screen  edi- 
tor is  moving  screen  data.  The  pointer 
to  this  buffer  is  stored  in   100,101 


(S64,S65)  during  the  routine. 

623  26F  GPRIOR 

Priority  selection  register,  shadow 
for  53275  (SDOIB).  Priority  options 
select  which  screen  objects  will  be  'in 
front'  of  others.  It  also  enables  you  to 
use  all  four  missiles  as  a  fifth  player 
and  allows  certain  overlapping  players 
to  have  different  colors  in  the  areas 
of  overlap.  You  add  your  options  up 
as  in  location  559,  prior  to  POKEing 
the  total  into  623. 

Locations  624  to  647  ($270  to 
$287)  are  used  for  game  controllers: 
paddle,  joystick  and  lightpen  values. 


624 


270 


PADDLO 


The  value  of  paddle  0  (paddles  are 
also  called  pots,  short  for  potentiom- 
eter); PEEK  624  returns  a  number  be- 
tween zero  and  228  ($E4),  increasing 
as  the  knob  is  turned  counter- 
clockwise. 


625 


271 


PADDLl 


This  and  the  next  six  bytes  are  the 
same  as  624,  but  for  the  other 
paddles. 


632 


278 


STICKO 


The  value  of  joystick  0.  STICK 
registers  are  shadow  locations  for  PIA 
locations  54016  and  34017 
($D300,$D301).  There  are  nine  pos- 
sible decimal  values  (representing  45 
degree  increments)  read  by  each 
joystick  register  (using  the  STICKn 
command).  ^

GAME  OF  THE  HOMTH 


l^ipp^i  .*i0Kmnrl 


The  Nerve  Game 

Countdown  on  ^our  dosswofd  sldn&. 
By  Jason  Sttantfnan 


The  object  of  the  Nerve 
Game  is  deceptively  sim- 
ple. You  must  complete 
eight  different  word-puzde 
cards  by  placing  letters  on  them  to 
spell  words — and  do  so  in  the  fewest 
turns.  Each  player  rolls  12  dice,  each 
with  one  letter  per  side.  Then  you 
place  the  letters  on  the  cards,  com- 
pleting words  in  a  crossword  fashion. 
Each  player  plays  the  same  eight 
cards  in  a  different  order.  Spaces  that 
must  be  filled  are  represented  by  a 
large  dot.  Spaces  that  arc  part  of  the 
same  word  are  either  touching  or  con- 
nected by  a  line. 

Now  for  the  nerve  part  of  the 
game:  after  you  complete  a  card,  you 
have  two  choices.  First,  you  can  just 
stop  your  turn.  \bu  will  be  credited 
with  all  the  cards  you  finished  and 
you  won't  have  to  do  those  cards  over 
lagain,  no  matter  what.  However,  go- 
ing on  means  that  you  risk  all  the 
cards  you  have  finished. 

If  your  time  runs  out  before  you 
finish  the  card  you're  on,  you  must 
re-do  all  the  cards  that  you  completed 
during  that  round.  But  since  you're 
playing  to  see  who  can  finish  the 
cards  in  the  fewest  turns,  sometimes 
it's  worth  the  risk.

AtariWriter  80 

Ultimate  80-column  word  processing  for  8-bit 
Review  by  Matthew  Ratcliff 


At  long  last  AtariWriter  80 
is  here.  Users  of  the  origi- 
nal AtariWriter  or  Atari - 
Writer  Plus  will  be  in- 
stantly familiar  with  AtariWriter  80. 
This  is  the  first  80-column  word 
processor  direct  from  Atari  for  their 
8-bit  home  computers. 

AtariWriter  80  costs  only  S49.95, 
but  that's  just  the  beginning  of  your 
start-up  investment.  You  need  Atari's 
$79.95  XEP80  box  and  a  good  80- 
column  composite  video  monitor — 
monochrome  is  preferred  and  costs 
about  $100.  Therefore,  adding  80- 
column  word  processing  to  your  Atari 
computer  can  easily  cost  more  than 
$200. 

FIRST  IMPRESSIONS 

The  AtariWriter  80  program  disk  is 
a  flippy.  The  48K  version  is  on  Side 
1,  and  the  130XE  (128K)  version  is  on 
Side  2.  The  130XE  version  of 
AtariWriter  80  provides  three  mem- 
ory banks  of  15872  bytes  each,  for  a 
total  edit  buffer  size  of  about  47K.  You 
manage  these  banks  by  entering  text 
into  one  buffer  until  it  is  full,  or  nearly 
so,  and  then  pressing  [START]  [B]  to 
select  the  next  bank. 

When  loading  a  very  large  docu- 
ment, AtariWriter  80  splits  it  evenly 
among  the  three  banks,  leaving  room 
in  each  buffer  for  the  document  to 
grow.  The  [OPTION]  [F]  command 
tells  AtariWriter  80  to  activate  its  free 


memory  clean-up  sequence,  which 
redistributes  the  file  evenly  among  the 
3  buffers.  This  isn't  as  elegant  as  it 
could  be,  but  is  quite  workable.  Un- 
fortunately, AtariWriter  80  does  not 
use  the  extra  memory  of  popular 
third-party  800XL  expansions  such  as 
the  256K  RAMbo  XL. 

The  98-page  manual  is  well-written 
and  has  a  complete  index.  AtariWriter 
80  also  includes  a  glossy  quick- 
reference  card  that  is  very  helpful.  It's 
all  that  most  AtariWriter  veterans  will 
need  to  navigate  AtariWriter  80  com- 
fortably. 

The  usual  create,  edit,  print,  and 
other  file  support  functions  are  avail- 
able from  AtariWriter  80's  main  menu. 
You  can  also  start  the  spell  checker  or 
mail  merge  utility  from  this  menu. 
The  program  disk  cannot  be  write- 
protected,  because  it  is  required  for 
temporary  storage  in  loading  the 
Proofreader  or  Mail  Merge  programs. 

When  editing,  the  [BREAK]  key 
forces  a  screen  redraw,  at  which  time 
AtariWriter  80  reformats  the  screen 
nicely.  But  while  inserting  text,  the 
display  is  not  always  updated  cor- 
rectly. 

PROOFREADER 

After  creating  a  file,  you  can  verify 
spelling  by  selecting  the  proofreader 
option  from  the  AtariWriter  80  menu. 
You  are  prompted  to  insert  the  pro- 
gram disk  into  drive  1.  AtariWriter  80 


first  writes  the  document  to  a  tem- 
porary file  on  the  program  disk,  and 
then  loads  the  Proofreader 

Generally  it  is  unwise  to  write  to 
your  main  program  disk.  However, 
AtariWriter  80  is  not  copy-protected. 
And  with  a  sector  copy  utility,  I  had 
no  problems  making  a  backup  copy 
of  the  master  program  and  dictionary 
disks.  The  manual  does  not  mention 
this,  however 

From  the  Proofreader  menu  you 
can  chose  to  correct  errors  interac- 
tively, highlight  errors  while  review- 
ing the  file,  or  send  a  list  of  spelling 
errors  to  the  printer.  Proofreader  is 
capable  of  adding  and  saving  a  user 
defined  personal  dictionary.  The 
menu  provides  options  for  listing  the 
directory  of  drive  1  or  2,  as  well  as 
loading  or  saving  AtariWriter  80  docu- 
ments for  additional  spell  checking 
work.  When  all  corrections  have  been 
made,  control  returns  to  AtariWriter 
80  for  continued  editing  of  the  origi- 
nal document,  with  spelling  changes 
in  place. 

MAIL  MERGE 

Mail  Merge  is  a  nice  database  facil- 
ity, geared  toward  the  creation  and 
management  of  "address  books,"  but 
easily  modified  to  your  individual 
tastes.  Mail  Merge  presents  a  menu 
from  which  you  can  choose  to  cre- 
ate, edit,  and  manage  mailing  lists. 
Multiple  mailing  list  files  are  simple 


DECEMBER  1989/JANUARY  1990

to  define,  each  with  different  field 
names  and  sizes. 

This  miniature  database  supports  a 
maximum  of  15  fields.  The  field 
names  can  have  as  many  as  12  charac- 
ters, with  data  fields  of  20  characters 
or  less.  A  total  of  255  records  fit  in 
one  address  file. 

Mail  Merge  presents  a  default  rec- 
ord format,  quite  suitable  for  almost 
any  address  book.  Address  files  are 
easily  updated,  cataloged  and  printed. 
After  creating  a  satisfactory  template, 
you  enter  data  to  fill  the  records.  Save 
the  address  book  to  disk,  and  it  can 
be  merged  with  AtariWriter  80  docu- 
ments later 

A  Mail  Merge  file  is  easily  tied  into 
an  AtariWriter  80  document  to  create 
fonn  letters,  or  generate  customer  bill- 
ing. While  you  edit,  pressing  [OP- 
TION] [M]  tells  AtariWriter  80  to  insert 
one  of  the  fields  from  an  address  file. 
This  keypress  is  immediately  followed 
by  the  desired  field  number  to  print 
in  the  document. 

When  printing,  AtariWriter  80 
prompts  for  the  name  of  the  Mail 
Merge  file  from  which  to  import  the 
fields.  If  the  Mail  Merge  file  contains 
six  records  the  document  will  be 
printed  six  times,  using  the  proper 
fields  from  each  record  for  each  copy. 

PRINTING 

AtariWriter  80  prints  documents 
through  the  XEP80's  printer  interface 
or  through  a  standard  Atari  printer 
adapter,  such  as  Atari's  850  interface 
or  ICD's  P:R:  Connection.  When  the 
print  command  is  selected,  you 
specify  whether  to  use  the  XEP80  or 
other  printer  port.  No  print  problems 
were  experienced  while  printing 
through  the  XEPSO's  interface  port. 
It  also  works  fine  with  the  printer  in- 
terface of  ICD's  MIO  board. 

AtariWriter  80  supports  all  Atari 
printers,  as  well  as  the  Epson  FX-80, 
IDS  Microprism  480,  and  Juki  6100. 
Pressing  [SELECT]  while  booting 
AtariWriter  80  brings  up  the  Custom 
Printer  Editor,  which  lets  you  create 
a  custom  printer  driver  if  your  printer 


has  a  readable  manual. 

Out  of  the  box,  AtariWriter  80  sup- 
ports condensed,  proportional,  and 
elite  type  fonts.  Up  to  nine  fonts  are 
supported.  Some  of  the  additional 
font  selection  commands  can  be  used 
to  enable  different  color  printing  on 
an  NXIOOO  Rainbow  printer  The  Cus- 
tom Printer  Editor  does  not  allow  you 
to  load  and  modify  a  predefined 
driver  So,  creating  an  Epson  printer 
driver  with  the  addition  of  NLQ, 
italics,  and  other  fonts  requires  build- 
ing everything  from  the  ground  up. 
AtariWriter  80  is  capable  of  loading 
AtariWriter  and  AtariWriter  Plus  files 
with  no  problems.  AtariWriter  80  em- 
ploys a  separate  global  format  menu, 
just  like  AtariWriter  Plus.  After  load- 
ing an  AtariWriter  file,  the  top  line  of 
control  codes  used  for  global  format- 
ting needs  to  be  deleted.  No  other 
compatibility  problems  should  occur 

AtariWriter  80  provides  an  elegant 
set  of  block  operations.  After  mark- 
ing the  top  of  a  block  of  text,  the 
writer  moves  to  the  end  of  the  block 
and  selects  an  option.  Commands 
supported  are  alphabetize,  count 
words,  delete,  duplicate,  move,  or  save 
the  block  of  memory  to  a  file.  A  block 
of  memory  cannot  cross  a  memory 
bank  boundary  in  the  130XE  version. 
However,  AtariWriter  80  will  copy  or 
move  blocks  between  different  banks 
of  memory. 

NEAR  WYSIWYG  PREVIEWS 

AtariWriter  80 's  print  preview  is 
very  nearly  a  true  "what  you  see  is 
what  you  get"  (WYSIWYG)  display 
If  the  document  has  a  second  set  of 
margins  defined,  the  XEP80's  preview 
screen  indeed  shows  dual  columns 
simultaneously.  If  the  total  page  width 
is  80  columns  or  less,  the  document 
preview  will  be  displayed  completely 
on  the  XEPSO's  screen.  For  wider 
documents,  you  must  scroll  horizon- 
tally to  view  complete  lines,  as  in 
older  versions  of  AtariWriter 

SUMMING  UP 

AtariWriter  80  seems  to  be  a  pretty 


solid  product.  The  only  noticeable 
glitch  of  AtariWriter  80  is  that  often, 
while  pressing  [CONTROL]  [DOWN 
ARROW]  to  scroll  the  display  down 
one  line  at  a  time,  the  display  jumps 
to  the  end  of  the  document,  as  if  [SE- 
LECT] [B]  were  pressed.  This  is  best 
avoided  by  employing  the  [OPTION] 
[DOWN  ARROW]  to  move  down  a 
page  at  a  time,  a  reliable  function. 

While  composing  this  article,  I  be- 
gan deleting  some  characters  with 
[CONTROL]  [DELETE].  Garbage 
started  appearing  at  the  bottom  of  the 
display,  and  soon  the  lower  half  of  the 
screen  was  a  mess.  However,  all  my 
display  problems  cleared  up  when  I 
shut  off  the  1040ST  system  nearby.  I 
suspect  the  ST  was  creating  some  in- 
terference with  communications  be- 
tween the  800XL  and  XEP80. 

Maybe  because  I  don't  do  much 
word  processing  on  the  8-bit  any 
more,  it  seemed  to  me  that  AtariWriter 
80  misses  keys  occasionally.  When 
typing  rapidly,  a  blank  space  may 
show  up  instead  of  the  letter  pressed, 
or  letters  are  missing  entirely.  The  keys 
on  my  800XL  are  much  stiffer  than 
on  my  PC  AT  compatible,  so  the  cause 
could  be  my  lack  of  regular  practice 
on  the  800XL.  I  also  experienced 
similar  problems  with  Turboword 
from  Micromiser 

AtariWriter  80  is  the  best  80 
column  word  processor  for  the  8-bit 
Atari.  Turboword  is  good,  but 
AtariWriter  80  comes  from  a  rich  tra- 
dition of  superb  word  processors.  It 
just  feels  like  a  solid,  tightly  integrated 
product.  If  you  have  an  XEP80  lan- 
guishing in  the  linen  closet,  get  it  out, 
purchase  AtariWriter  80,  and  put  it  to 
work.  Once  you  start  word  process- 
ing in  80  columns,  you  will  never 
want  to  work  with  40  columns 
again.  a

PC  Print 

Clean  printouts  from  your  IBM  downloads. 
By  John  West 


Print  downloaded  IBM  format  text  files 
easily — without  the  extra  spaces  and 
RETURNS  found  in  standard  ASCII  files. 
PC  Print  replaces  the  most  troublesome 
control  characters  even  as  the  file 
prints.  This  BASIC  program  works  on 
all  8-bit  Atari  computers  of  any  mem- 
ory size,  with  disk  drive  and  printer. 


If  you  use  a  modem,  as  I  do, 
then  you've  probably  had  to 
cope  with  IBM  text  files  at 
some  point.  Even  some  text 
files  for  the  8-bit  Atari  are  converted 
to  this  standard  ASCII  format  when 
posted  on  telecommunications  serv- 
ices such  as  CompuServe  and  GEnie. 
You  can  download  files  from  other 
computers  (from  non-Atari  bulletin 
boards)  and  use  them.  But,  most  text 
files  you  download  have  been  writ- 
ten on  IBMs,  which  use  CTRL-M  and 
CTRL-J  to  do  the  same  thing  Atari  does 
with  a  155. 

I've  spent  many  an  hour  taking  out 


CTRL-M  and  CTRL-J  characters  from 
IBM  text  files  after  loading  them  into 
a  word  processor.  It  seems  that  almost 
none  of  the  Atari  word  processors  al- 
low you  to  globally  replace  a  [RE- 
TURN]. {The  First  XLEnt  Word 
Processor  is  one  we  know  of  that  will 
replace  RETURNS.  We  always  keep  a 
copy  handy  for  just  that  purpose.— 
ANTIC  ED) 

One  time  I  wrote  my  own  program 
to  simultaneously  strip  out  the  CTRL- 
M's  and  J's,  insert  a  CHR«(155)  and 
save  the  file.  This  takes  a  lot  of  time 
and  extra  disk  space,  however  Since 
all  I  usually  want  to  do  is  print  the  file, 


I  finally  created  PC  Print,  a  program 
that  replaces  the  troublesome  charac- 
ters while  the  file  is  being  sent  to  the 
printer. 

GEHING  STARTED 

Type  in  Listing  1,  PCPRINTBAS, 
check  it  with  TYPO  II,  and  SAVE  a 
copy  to  disk.  When  you  RUN  this  BA- 
SIC program  it  will  create  a  file  named 
PCPRINT.COM  and  write  it  to  the  disk 
in  drive  1. 

Rename  this  fUe  to  AUTORUN.SYS, 
using  Atari  DOS  selection  E.  Then 
when  you  reboot,  PC  Print  will  load 
and  run  automatically.  (You  can  also 
use  DOS  option  L  to  load 
PCPRINT.COM,  without  renaming  it.) 

If  you  have  an  Assembler  cartridge, 
such  as  MAC/65, you  may  type  in  the 
source  code  shown  in  Listing  2  and 
assemble  it.  Listing  2  is  included 
primarily  for  MAC/65  programmers. 
You  do  not  need  to  type  in  Listing  2 
to  use  PC  Print. 

Then,  copy  any  IBM  text  file  to  the 
printer  and  it  will  be  converted  "on 
the  fly."  From  DOS,  use  selection  C, 
and  when  specifying  the  destination 
device  use  P:  to  send  the  file  to  the 
printer.  For  example,  type: 

D:IBMTEXTDOC,P:  [RETURN]. 

Press  [RESET]  to  disable  this  special 
handler.

HOW  IT  WORKS 

PC  Print  takes  each  byte  sent  to  the 
printer,  checks  it  and  transforms  any 
CTRL-M  (13)  into  a  0,  which  the 
printer  ignores.  Any  CTRL-J  (10) 
characters  are  transformed  into  an 
Atari  carriage  return  character  (155). 
Now  you  can  simply  copy  those  IBM 
ASCII  files  directly  to  the  printer, 
without  all  that  annoying  double 
spacing  caused  by  the  CTRL-M,  CTRL- 


Copy  a  text 

file  to 

the  printer 

and  it  will  be 

converted 

"on  the  fly." 


J  sequences. 

This  is  done  by  redirecting  the 
printer  handler  vector  in  Atari's  low 
memory  to  our  own  routine  in  Page 
6.  All  characters  other  than  the  CTRL- 
M  and  CTRL-J  sequences  are  passed 
on  to  the  operating  system,  which 
handles  the  actual  printing. 

If  you  don't  have  a  modem,  I  sug- 
gest you  get  one.  It  will  open  a  fas- 
cinating new  world  of  computing,  af- 
fording the  opportunity  to  share 
information  with  many  other  Atari 
and  non-Atari  computer  users.  Many 
popular  bulletin  board  systems,  often 
run  by  Atari  computer  clubs,  are 
found  all  across  the  US,  running  on 
Atari  8-bit  machines.  A

SUPER  DISK  BONUS 


Naval  Battle 

Slick,  flashy  version  of  an  old  favorite. 
By  John  Hutchinson  and  David  Rajala 


Naval  Battle 

This  issue's  super-duper 
third  Disk  Bonus  is  Naval 
Battle,  a  flashy,  colorful 
version  of  the  classic  Bat- 
tleship game.  This  BASIC  game 
works  on  8-bit  Atari  computers  with 
at  least  48K  memory  and  disk  drive. 
A  joystick  is  required,  or  two 
joysticks  are  optional. 

Remember  that  game  you  used  to 
play  with  pencil  and  paper  where 
you  hid  a  battleship  and  other  sea- 
going craft  on  a  grid?  You  and  your 
opponent  would  take  turns  firing 
salvos  by  calling  out  coordinates  like 
'  A-1"  or  "G-9,"  trying  intendy  to  find 
and  sink  each  other's  ships.  It  was 
fun,  but  drawing  up  the  grids  was 
often  just  as  difficult  as  finding 
someone  to  play  with. 

Well,  now  all  you  frustrated 
would-be  admirals  can  experience 
the  thrills  of  combat  on  the  high  seas 
with  Naval  Battle.  This  extra-slick 
Atari  8-bit  version  boasts  sharp 
graphics  and  sounds,  complete  with 
the  boom  of  naval  artillery  and  the 
splash  of  a  watery  miss. 


The  authors  of  this  impressive  ef- 
fort have  plenty  of  military  back- 
ground to  draw  from.  David  Rajala 
is  a  retired  military  officer,  currently 
working  as  a  defense  analyst  in 
Washington,  D.C.  Major  John  Hutch- 
inson is  an  Operations  Research- 
Systems  Analyst  for  the  Army. 

GEHING  STARTED 

The  entire  back  side  of  the  Antic 
Monthly  Disk  has  been  used  for  Na- 
val Battle,  which  will  boot  automat- 
ically, Just  put  the  Antic  Disk  in  drive 
one  with  side  B  up  (label  side 
down).  Turn  the  computer  off  and 
then  on  again  with  BASIC  (XL/XE 
owners  don't  hold  down  [OPTION]) 
and  the  game  loads  and  runs  auto- 
matically. 

You  can  try  your  skill  against  a 
computer  opponent,  compete  with 
another  human  player,  or  just  sit 
back  and  watch  the  computer  play 
both  roles  all  by  itself.  There  is  even 
a  choice  of  difficulty  levels  for  hand- 
icapping young  or  inexperienced 
players. 

Use  your  joystick  to  select  from 
the  game  options.  Press  the  [SPACE- 
BAR] to  pause  the  game  or  then  re- 
sume. Press  [ESCAPE]  or  [RESET]  to 
end  the  game  in  progress. 

PLAY  OPTIONS 

DEMO  MODE  pits  the  computer 
against  itself.  To  join  in  the  action 
yourself,  choose  1  PLAYER  mode  to 
compete  against  the  computer,  or  2

ANTIC,  THE  ATARI  RESOURCE 


PLAYER  to  play  against  another 
human. 

In  two-player  mode  you  have  the 
further  option  of  using  two 
joysticks,  or  sharing  a  single  stick. 
The  computer  hides  the  ships  for 
both  players,  so  you  don't  have  to 
worry  about  accidentally  seeing  the 
other  player's  layout.  Players  also  get 
to  choose  different  difficulty  levels. 

The  three  difficulty  levels  range 
from  ENSIGN,  the  easiest,  to  CAP- 
TMN  and  ADMIRAL.  As  the  level  in- 
creases, the  human  player  is  allowed 
less  time  to  place  shots — and  the 
computer  uses  more  artificial  logic 
in  planning  its  shots.  If  you  beat  the 
computer  consistendy  at  ADMIRAL 
level  you  should  join  the  Navy.  Ifour 
country  needs  you! 

Other  options  let  you  choose  be- 
tween playing  with  sound  effects  or 
without.  If  you  would  rather  fight 
your  batde  in  relative  silence  you 
will  considerably  speed  up  the  proc- 
ess as  well. 

SHIP  PLACEMENT 

In  single  player  mode  you  can 
place  your  ships  yourself,  using  the 
joystick,  or  let  the  computer  do  it. 
Your  fleet  consists  of  five  ships  of 
varying  lengths — an  Aircraft  Carrier 
(5  squares),  a  Battleship  (4  squares), 
a  Destroyer  (3  squares),  a  Submarine 
(3  squares)  and  a  PT  Boat  (2  squares). 
These  shif>s  are  all  drawn  in  detail — 
you  can  even  see  the  tiny  planes  on 
the  deck  of  the  carrien 

You  can  place  each  ship  either 
horizontally  or  vertically  by  posi- 
tioning a  flashing  cursor  on  the 
game  grid  and  pressing  the  joystick 
trigger.  Once  all  your  ships  are  posi- 
tioned, the  computer  asks  if  the 
placement  is  okay,  giving  you  a 
chance  to  rc-position  your  ships. 

PLAYING  NAVAL  BAHLE 

Player  number  one  (or  the  human 
player  in  a  one-player  game)  always 
goes  fust.  Using  your  joystick,  move 


the  flashing  cursor  across  your  op- 
ponent's green  game  grid.  Select  a 
position  where  you  think  he  might 
have  hidden  a  ship  and  press  the 
joystick  button.  You'll  hear  the 
sound  of  a  naval  gun  being  fired,  fol- 
lowed by  either  a  splash  if  you 
missed  or  explosion  if  you  scored  a 
hit.  The  game  grid  will  display  a 
white  square  for  a  miss.  A  red  square 
indicates  a  hit. 


gies  is  to  first  go  after  your  oppo- 
nent's largest  remaining  ship,  select- 
ing grid  squares  where  the  ship 
could  fit  both  vertically  and 
horizontally.  "Vbu  can  also  stagger 
your  shots  in  a  checkerboard  pat- 
tern. Try  to  avoid  placing  two  shots 
side-by-side.  This  way  you  can  logi- 
cally eliminate  squares  where  your 
opponent's  ships  cannot  possibly  fit, 
without  having  to  actually  waste  a 


Experience  combat  complete  with 

the  boom  of  artillery  and  the  splash 

of  a  watery  miss. 


If  you  hit  a  ship,  one  segment  of 
the  appropriate  ship  on  the  Hit  In- 
dicator will  also  turn  red.  The  Hit 
Indicator  shows  you  how  many  sec- 
tions of  the  ship  have  been  hit,  but 
not  which  ones.  "Vbu'U  have  to  fig- 
ure that  out  by  trial  and  error. 

Then  your  opponent  takes  his 
turn.  If  you  are  playing  against  the 
computer;  your  ships  will  remain 
visible  on  the  blue  game  grid.  If  you 
are  playing  a  two  player  game,  both 
opponent's  ships  will  remain  hidden 
from  view.  You  and  your  opponent 
will  continue  to  take  turns  until  the 
game  ends. 

The  first  player  to  sink  all  of  his 
opponent's  ships  is  the  winner  The 
computer  will  then  briefly  display 
the  winner's  ship  placement  so  the 
loser  can  see  how  close  his  shots 
were.  You  can  then  either  change 
your  game  options,  or  start  another 
exciting  naval  encounter  with  the 
same  settings. 

STRATEGY  TIPS 

When  playing  Naval  Battle  you 
want  to  maximize  the  effectiveness 
of  your  shots.  One  of  the  best  strate- 


shot  on  them. 

\bur  computer  opponent  uses 
this  strategy  to  find  the  most  logical 
hiding  spots  for  your  ships.  A  series 
of  "artificial  logic"  routines  help 
simulate  the  human  decision  mak- 
ing process. 

The  computer  will  vary  its  ship 
placement  each  game  and  may  even 
place  its  ships  side-by-side  in  an  at- 
tempt to  fool  you.  The  computer 
should  prove  a  worthy  opponent, 
but  it  is  certainly  not  infellible.  Fol- 
low its  lead  and  use  logic  in  placing 
your  shots,  and  you  should  be  able 
to  beat  it.

Automating  Atari 

Programming  WIMA  with  a  130XE. 
By  Mark  Gierhart 


As  a  result  of  network  pro- 
gramming changes,  man- 
agement at  radio  station 
WIMA  in  Lima,  Ohio  pre- 
sented our  engineering  department 
with  a  real  challenge.  We  needed  to 
resurrect  our  old  automation  system 
so  it  could  handle  local  programming 
for  six  hours  every  night.  And  it  had 
to  be  on-line  in  two  to  three  months! 
The  engineering  department  consists 
of  only  two  full-time  engineers,  Dick 
Knowles  and  myself,  which  meant  we 
had  our  work  cut  out  for  us. 

As  the  first  step,  we  examined  our 
options.  We  could  repair  the  outdated 
system  which  had  last  been  in  use 
several  years  ago,  or  we  could  design 
and  construct  our  own  system  using 
the  salvageable  parts  from  the  old  au- 
tomation unit.  Either  way,  the  time 
constraints  would  make  it  a  difficult 
job. 

After  analyzing  the  existing  system 
we  determined  that  many  of  the  con- 
trol parts  which  needed  repair  were 
either  no  longer  available  or  difficult 
to  come  by  at  best,  and  the  time  re- 
quired to  get  the  parts  available  would 
put  us  over  our  deadline.  This  left  us 
only  one  option,  designing  a  new 
system. 

With  the  choice  made  clear,  our 
task  was  still  no  easier  than  before.  We 
needed  to  find  a  "brain"  or  controller 
for  our  system,  and  it  had  to  meet 
several  criteria.  It  had  to  be  easy  to

at  WIMA  radio. 


use,  reliable,  and  most  important, 
cost-effective.  This  brain  had  to  con- 
trol several  music  tape  decks,  com- 
mercial carousel  decks,  voice  tape 
decks  and  satellite  network  news 
feeds,  all  with  little  or  no  outside 
operator  assistance. 

The  system  would  require  some 
type  of  microprocessor  controller  to 
allow  storage  of  program  events  and 
time  schedules.  Having  had  previous 
experience  with  the  Atari  8-bit  com- 
puter's capabilities,  we  elected  to  go 
with  an  Atari  130XE  computer  as  the 


main  brain  of  our  automation  system. 

T30XE  BRAIN 

The  Atari  130XE  had  all  the  features 
we  needed  for  the  project,  including 
the  low  price  tag.  To  complete  the  sys- 
tem, a  disk  drive,  printer  and  several 
cartridges  were  included  in  our 
purchase. 

At  this  point  we  were  ready  to  start 
working  towards  our  goal,  building 
our  broadcast  automation  system  us- 
ing our  8-bit  computer  My  task  was 
to  write  the  software  and  design  the 


ANTIC,  THE  ATARI  RESOURCE 


computer  interfacing  to  accommo- 
date Dick's  audio  and  switching 
designs. 

Having  done  some  programming  in 
BASIC  XE  from  ICD/OSS,  I  decided 
that  would  be  the  language  to  use  for 
my  automation  program.  BASIC  XE 
gave  me  several  powerful  features  I 
wanted,  including  the  EXTEND  com- 
mand (which  uses  the  130's  extra 
RAM),  the  FAST  command  (which 
speeds  up  the  BASIC),  and  several 
variable  functions  which  standard 
Atari  BASIC  doesn't  allow. 

I  also  needed  the  ability  to  access 
the  clock  output  functions  of  the  Atari 
I3OXE,  giving  the  program  accurate 
time  and  date  commands.  I  decided 
to  try  ICD's  R-Time  8  module.  With 
ICD  SpartaDOS  I  now  had  access  to 
both  the  time  and  date  either  format- 
ted or  unformatted. 

I  now  started  on  the  programming. 
First  I  had  to  find  a  way  to  get  com- 
plete control  over  each  of  the  audio 
sources  needed  for  the  system.  Being 
in  a  somewhat  high-noise,  high-RF 
environment,  I  decided  to  use  the 
Atari's  built-in  sound  generator,  using 
small,  cheaply-constructed  tone 
decoder  interfaces. 

Using  a  series  of  Atari  POKE  com- 
mands, I  could  produce  just  about  any 
tone  from  lOOhz  to  well  over  lOkhz. 
The  computer  sends  out  the  given 
tone,  which  turns  on  the  tone 
decoder,  closing  its  relay  contacts  to 
start,  stop,  or  perform  any  other 
specified  function  on  the  tape 
machines.  Thanks  to  the  Atari's  fine 
four-channel  audio  sound  system,  I 
was  now  able  to  control  any  outside 
source. 

Now  I  needed  a  reliable  means  of 
interfacing  the  Atari  with  the  outside 
world.  I  elected  to  use  the  Atari's  pad- 
dle (joystick)  ports.  These  ports  have 
an  internal  voltage  divider  circuit 
which  gives  the  computer  a  number 
values  that  vary  with  any  change  in 
voltage  into  the  port.  By  placing  a  dif- 
ferent resistance  in  each  line  of  the  in- 
terface, and  using  the  PADDLE(x) 
command,  I  was  able  to  distinguish 

DECEMBER  1989/JANUARY  1990 


each  individual  signal  coming  from 
the  tape  machines. 

SOFTWARE 

Once  the  interfacing  was  complete 
it  was  time  to  sit  down  and  write  the 
program.  The  program,  which  I  call 
AUTOMATE,  is  completely  menu- 
driven.  Some  of  the  special  features 
of  the  program  include  an  auto  start/ 
stop  mode,  print  to  screen/printer 
mode,  and  an  enlarged  print  mode. 
Also,  all  of  the  Atari's  special  function 
keys  were  incorporated  into  the  pro- 
gram for  ease  of  operation. 

The  R-Time  8  module  functions 
were  used  constantly  throughout  the 
program.  The  Atari  130XE  with  this 
module  is  responsible  for  airing  a  net- 
work satellite  news  feed  at  the  top  of 
each  hour  Also,  this  module  makes 
automatic  starting  and  stopping  of  the 
system  at  any  given  time  a  reality. 

Another  special  feature  of  the  pro- 
gram was  the  enlarged  print  mode.  By 
pressing  a  single  key  while  in  the 
menu,  the  operator  could  bring  up  a 
Graphics  17  screen,  enlarging  all  the 
menu  text.  I  included  this  option  in 
the  software  to  aid  a  vision-impaired 
person  working  here  at  the  station. 

After  about  a  month  and  a  half  of 
"late  night"programmingI  was  ready 
to  hook  AUTOMATE  into  the  rest  of 
the  automation  system.  Dick  had  a 
well-designed  audio/switching  system 
ready  and  waiting  for  the  program's 
completion. 

Within  a  week,  we  had  both  the 
Atari  130XE  and  the  audio/switching 
system  up  and  running.  To  actually 
see  the  computer  stepping  through 
and  playing  each  programmed  event 
was  a  dream  come  true.  The  hard 
work  and  many  long  hours  had  paid 
off. 

Future  plans  under  consideration 
include  interfacing  the  automation 
system  with  our  accounting  and  bill- 
ing department.  This  will  allow  direct 
billing  and  monitoring  of  the  station's 
commercial  inventory.  The  station  al- 
ready uses  an  Atari  for  inventory, 
word  processing  and  scheduling.  A

DOUBLE  DISK  BONUS 


Antic  Numerologist 


See  how  your  name  and  dates  add  up. 
By  Clifton  Oyamot 


Once  again  ancient  mys- 
ticism meets  modern 
science,  this  time  in  tlie 
form  of  your  Atari 
Numerologist,  this  issue's  second  Su- 
per Disk  Bonus.  This  extra-long  BA- 
SIC program  can  be  found  on  your 
monthly  Antic  Disk,  ready  to  RUN. 
Programmer  Clifton  Oyamot  is  a  17- 
year-old  senior  at  Rancho  High 
School  in  Las  Vegas,  Nevada.  This  is 
his  first  appearance  in  Antic. 

Numerology,  in  its  present  form, 
can  trace  its  origins  to  the  6th  cen- 
tury B.C.  and  to  the  great  mathema- 
tician Pythagoras.  Numerologists 
contend  that  all  things  can  be 
reduced  to  numbers,  and  under- 
stood from  there.  This  applies  par- 
ticularly well  to  names  and  dates.  By 
analyzing  the  numbers  in  your  name 
and  birthdate,  a  supposedly  accurate 
personal  portrait  can  painted. 

Numerology  can  be  seen  as  a  sort 
of  mathematical  astrology.  If  you  be- 
lieve astrology  is  a  waste  of  time,  you 
won't  feel  much  differently  about 
Antic  Numerologist.  We  are  present- 
ing this  program  strictly  for  its  en- 
tertainment value.  However,  it  occa- 
sionally does  seem  to  come  up  with 
some  interesting  insights.  (See  box.) 

When  you  run  Antic  Numerolo- 
gist, you  are  presented  with  two 
choices.  Name  and  Date.  Name  gives 
you  an  analysis  of  your  character. 


The  prompts  ask  for  your  first,  mid- 
dle, and  last  names.  Omit  titles  and 
such  like  Jr.  or  III,  spaces,  and  other 
non-letter  characters  which  may  oc- 
cur. Combine  separate  names  into 
one  word  (e.g.  Maryann).  If  you  lack 
a  middle  name,  just  enter  a  space. 
You  are  then  asked  for  your  birth- 
date.  Enter  your  birth  month  in  nu- 
merical form  0anuary  =    1,  etc.). 


Also,  enter  the  full  year,  not  the  two- 
digit  abbreviation. 

After  all  the  information  has  been 
entered,  your  Atari  wDl  make  the 
necessary  calculations,  which  can 
become  tedious  and  involved  when 
done  by  hand.  Finally,  the  Atari  in- 
terprets the  results  for  you,  display- 
ing the  interpretation  on  screen.  If 
you  like,  you  can  then  print  the  re- 


Gems  from  the  Antic  Numerologist 

Richard  Milhous  Nixon,  1/9/1913 

When  denied  your  wishes,  you  may  scheme  to  get  your 
ways.  Despite  this,  your  natural  inclination  is  to  help  people. 
.  .  .If  not  careful,  however,  you  can  lead  a  life  of  disappoint- 
ments and  depression. 

George  Washington,  2/22/1732 

You  are  the  pioneer,  the  leader,  the  captain.  You  are  highly 
original  and  creative  and  you  possess  the  drive  to  put  your 
ideas  into  practice.  You  are  highly  ambitious. 

Ronald  Wilson  Reagan,  2/6/1911 

You  are  naturally  friendly  and  sociable.  You  also  have  a 
need  to  fix  things  when  they  are  not  quite  perfect.  Peace  and 
quiet  are  what  you  yearn  for.  .  .  .You  try  to  maintain  harmony. 
Without  being  aggressive,  you  are  still  able  to  gather  all  that 
you  need,  including  many  friends.

YOUR  ANALYSIS 

The  analysis  is  broken  into  four 
areas.  The  Soul  Urge  describes  the 
motives  that  underlay  your  actions 
in  life.  The  Quiescent  Self  is  what 
you  do  or  think  about  when  alone. 
Your  Expression  is  how  you  appear 
to  the  outside  world  and,  quite  ap- 
propriately, how  you  express  your- 
self. Finally,  your  Life  Path  tells  of 
your  purpose  in  life.  If  you  wish  to 
have  a  hard  copy  of  the  results,  press 
[p]  at  the  prompt. 

The  second,  and  more  pedestrian, 
option.  Date,  is  more  like  a  horo- 
scope. Antic  Numerologist  will  ask 
for  your  birthdate  and  for  the  pres- 
ent date.  From  there,  it  will  give  you 
a  forecast  for  the  year,  month,  or 
day,  whichever  you  choose.  The 
message  divined  should  be  inter- 
preted according  to  the  particular 
time  frame,  whether  long-term  or 
short-term. 

The  Atari  Numerologist  is  by  no 
means  omnipotent,  but  coupled 
with  its  calculation  power  and  the 
cleverly  general  and  flattering 
responses,  you  sometimes  might 
find  yourself  amazed  by  the  pro- 
gram's accuracy.  Have  fun  delving 
into  the  psyche  of  friends  and  fam- 
ily and  perhaps  even  gain  a  few  valu- 
able insights  into  those  around  you.

Chemistry  Tutor 

Learn  your  ions,  stoichiometry  and  balanced  equations. 
By  John  Kennedy 


In  the  April,  1989  issue  of 
Antic  we  printed  Periodic 
Madness,  which  drilled  stu- 
dents about  chemical  ele- 
ments, their  symbols  and  atomic 
masses  as  shown  on  the  Periodic  Ta- 
ble of  the  Elements.  Now,  John 
Kennedy's  Chemistry  Tutor  takes 
smdents  several  steps  further,  into 
the  realm  of  ions,  stoichiometry  and 
balanced  equations. 

Chemistry  Tutor  is  a  BASIC  pro- 
gram, but  far  too  long  for  a  type-in. 
The  program  can  easily  be  RUN 
straight  from  the  Antic  Monthly 
Disk — just  press  the  number  to  the 
right  of  CHEMTUTR.BAS  on  the 
menu,  and  press  [RETURN].  Your 
tutor  will  LOAD  and  RUN  right  away. 

However,  actually  using  the  tutor 
won't  be  so  easy,  unless  you  already 
have  a  basic  understanding  of  begin- 
ning chemistry  and  stoichiometry 
(proportional  weights  and  measures 
involved  in  chemical  activity,)  and 
hence  the  science  of  balancing 
equations. 

Author  John  Kennedy  teaches 
Chemistry',  Physics  and  Computer 
Programming  at  Northwestern  High 
School  near  Springfield,  Ohio.  He 
developed  the  Chemistry  Tutor  to 
help  his  beginning  chemistry  stu- 
dents who  had  trouble  writing  and 
balancing  equations  and  solving 
mass-mass  problems.  He  says,  "I 
wanted  the  program  to  provide  a  va- 
riety of  questions  and  respond  to  in-

correct  answers  with  helpful  su^es- 
tions.  The  program  also  had  to  be 
easy  to  use,  even  by  students  with 
little  experience  with  computers." 
Thanks  to  the  8-bit  Atari's  graphics, 
the  resulting  program  was  both 
educational  and  colorful. 

USING  THE  PROGRAM 

After  the  title  screen,  a  menu  dis- 
plays the  following  choices:  Name 
Ions,  Write  Symbols  and  Charges  tor 
Ions,  Write  Chemical  Formulas, 
Write  Chemical  Equations,  Stoichio- 
metric Calculations,  and  End  Pro- 
gram. Pressing  the  [OPTION]  key  cy- 
cles through  the  choices.  When  the 
pointer  is  at  the  desired  choice,  press 
the  [SELECT]  key 

The  first  three  choices  each  give 
a  sequence  of  10  questions,  display- 
ing a  running  total  of  right  and 
wrong  answers.  Name  Ions  gives  the 
ion's  symbol  and  charge,  and  the 
user  must  name  the  ion.  For  exam- 
ple, the  symbol  CIO3  (charge  -I) 
must  be  identified  as  CHLORATE. 


DECEMBER  1989 /JANUARY  1990 


33 


The  program  uses  the  Stock  sys- 
tem, in  which  elements  with  more 
than  one  positive  oxidation  state  are 
identified  by  Roman  numerals.  For 
example,  iron  with  a  +  2  oxidation 
number  would  be  designated  as  Iron 
(II).  Leave  a  space  between  the  name 
and  the  parenthesis.  If  an  incorrect 
answer  is  entered  when  naming  or 
writing  symbols  for  ions,  the  correct 
answer  is  displayed  in  the  error  win- 
dow and  your  score  is  shown. 

In  Write  Symbols  and  Charges  for 
Ions,  the  program  gives  the  name  of 
an  ion,  and  the  user  must  enter  the 
symbol  and  then  the  charge  of  that 
ion.  Both  must  be  correct  to  receive 
credit.  If  the  symbol  for  CAR- 
BONATE is  correctly  entered  as  CO3, 
the  user  will  then  be  asked  for  the 
charge — in  this  case,  -2. 

Use  a  minus  sign  to  designate 
negative  charges.  A  plus  sign  for 
positive  charges  is  optional.  For  this 
section,  all  numbers  typed  will  ap- 
pear as  subscripts.  Letters  will  be  in 
lower  case,  with  the  [SHIFT]  key 
used  to  produce  capitals — the  ab- 
breviations of  the  elements  must  be 
correctly  capitalized. 

FORMULAS  &  EQUATIONS 

The  three  options  on  balancing 
equations  and  stoichiometry  give 
one  question  at  a  time.  Once  a  ques- 
tion has  been  completed,  the  pro- 
gram asks  if  you  want  to  do  another. 

When  the  Write  Chemical  For- 
mulas or  the  Write  Chemical  Equa- 
tions options  are  selected,  you  will 
be  asked  to  write  the  formulas  for 
chemical  compounds  such  as 
UTHIUM  CYANATE  (LiOCN)— or  to 
give  the  name  from  the  formula. 

Names  for  compounds  are  gener- 
ated randomly  from  positive  and 
negative  ions.  No  spaces  should  be 
used  when  writing  formulas.  When 
an  incorrect  formula  is  entered,  a 
hint  will  be  displayed  in  the  error 
window.  After  three  unsuccessful  at- 
tempts, the  correct  answer  is  dis- 


played. 

If  you  are  writing  equations,  you 
will  enter  the  formulas  for  two  reac- 
tants  and  two  products.  When  the 
complete  equation  is  in  the  display 
window,  a  cursor  will  appear  in 
front  of  the  first  compound.  Typing 
numbers  will  produce  standard 
numerals  as  coefficients.  Use  the 
[ARROW  KEYS]  to  move  from  one 
compound  to  another  until  the 
equation  is  balanced.  If  you  leave  a 
blank  space  in  front  of  any  com- 
pound, it  will  be  interpreted  as  a 
number  1. 

If  the  equation  is  not  balanced,  a 
help  screen  will  be  shown  in  the  in- 
formation window.  This  screen  dis- 
plays the  number  of  each  ion  as  a 
reactant  and  as  a  product  and  if  the 
two  are  in  balance.  Each  time  a 
coefficient  is  changed  the  display  is 
updated.  When  the  display  shows  a 
YES  for  each  product  and  reactant, 
the  equation  is  balanced.  The  coeffi- 
cients must  be  reduced  to  their  least 
possible  values  (like  fractions)  to  be 
correct. 

Stoichiometric  Calculadons  first 
requires  that  an  equation  be  written 
and  balanced.  A  mass  for  one  com- 
poimd  is  given  and  you  are  asked  for 
the  required  or  produced  mass  of 
another  Entering  an  incorrect  an- 
swer will  begin  a  tutorial  w^hich 
leads  step  by  step  to  the  correct 
answer. 

PROGRAM  TAKE-APART 

Information  about  positive  and 
negative  ions  is  stored  in  DAIA  state- 
ments in  lines  100-910.  Each  state- 
ment consists  of  the  ion  name,  sym- 
bol, oxidation  number,  a  one  (1)  for 
a  polyatomic  ion  or  a  zero  (0)  for  a 
monatomic  ion,  and  the  atomic 
weight. 

The  variables  NN  and  NP  are  in- 
itialized in  line  45  to  the  number  of 
negative  and  positive  ions.  By  alter- 
ing these  numbers,  the  user  may  se- 
lect only  a  part  of  the  ion  list. 


Display  list  interrupts,  initialized 
in  lines  10000-11100,  are  used  to  pro- 
duce a  multicolored  Graphics  0 
screen  divided  into  four  windows: 
green  for  information,  yellow  for 
display,  red  for  error  messages,  and 
green  for  input.  Players  are  used 
throughout  the  program  to  add 
color  by  overlaying  tides.  Players  are 
also  used  as  cursors.  Two  important 
machine  language  routines  are 
MOVES  and  ZEROS  in  lines  50  and 
60.  These  are  used  to  position 
players  by  moving  and  erasing 
blocks  of  memory. 

A  special  character  set  is  used  to 
display  subscripts.  In  this  character 
set,  the  nimierals  0-9  are  redefined 
as  subscripts  and  the  control  charac- 
ters having  AIASCn  values  0-9  are 
the  standard  numerals.  Lines  75  and 
80  first  move  the  character  set  from 
ROM  and  then  make  these  changes.

Pro  teleprompting  with  his  Ataris. 
By  Japji  Singh  Khalsa. 


r-«n 


One  day  on  the  video 
set.  .  . 
"Hold  it!  Cut!.  .  .That 
just  isn't  going  to  work!" 
the  director  says  with  an  edge  of 
irritation. 

I  sense  a  change  coining. 

"We  can't  use  'Good  Evening^— they 
may  be  seeing  this  video  in  the 
morning." 

Rough  start.  I  go  into  edit  mode. 

"Okay  let's  say  'Good  day'.  .  . 
no.  .  .  'Hello'.  .  .  no  that's  too  for- 
mal. .  .  Nancy,  what  do  you  think?" 

The  scriptwriter  thoughtfully 
chews  on  her  pencil  for  a  moment, 
"How  about  'Hi'?" 

I  liked  'Hi'  so  I  make  the  change, 
trying  to  stay  one  step  ahead  of  the 
game. 

DECEMBER  1989/JANUARY  1990 


The  director  thinks  out  loud, 
"Hi?.  .  .hmmm.  .  .  yes,  yes,  that  has 
some  potential.  Okay  .  .  PROMPTER! 
we  want  to  change.  .  ." 

I  cut  him  off,  'Already  done." 

"Great!"  he  says.  I'm  sure  he  must 
be  thinking  "Boy,  is  this  guy  good" 

Good?  Yes.  But  that's  mostly  thanks 
to  the  "sute  of  the  art"  teleprompter 
that  I'm  using.  And  at  the  heart  of  this 
system  is  an  Atari  130XE  8-bit 
computer. 

But  let  me  backtrack  just  a  moment 
because  some  people  don't  even 
know  what  a  teleprompter  is.  A 
prompter  is  a  system  by  which  the 
actor — or  in  official  filmA'ideo  lingo, 
the  "talent"  —  can  actually  read  his 
script  while  pretending  to  have 
memorized  it,  looking  straight  at  the 


camera. 

The  oldest  form  of  a  prompter,  to 
my  limited  knowledge,  was  a  big 
piece  of  white  cardboard  called  a  cue 
card.  It  was  cumbersome  and  clunky 
and  it  was  difficult  to  make  changes. 
Also,  most  often  you'd  be  able  to  see 
that  the  talent  was  looking  off  to  the 
side  of  the  camera  reading  cue  cards. 

Eventually  someone  invented  a  sys- 
tem with  a  one-way  mirror,  where  a 
piece  of  optical-quality  glass  with  a 
special  mirror-Uke  coating  is  mounted 
at  a  4  5 -degree  angle  in  front  of  the 
camera  lens.  Mounted  underneath  the 
mirror  would  be  either  an  acetate 
scroll  with  the  script  written  on  it,  or 
a  video  monitor  displaying  the  script 
text. 

The  talent  looks  at  the  glass  (into 


35 


the  lens  of  the  camera)  and  sees  the 
reflected  script  as  it  scrolls  by.  At  the 
same  time,  the  special  mirror  coating 
and  the  angle  of  the  glass  lets  the  cam- 
era look  through  it  without  seeing  the 
script. 

The  current  state-of-the-art  system 
feeds  a  digital  image  of  the  script  to 
the  monitor  mounted  under  the  mir- 
ror. The  digital  revolution  in  prompt- 
ing started  in  1983-  A  company  in 
Wisconsin  wrote  a  program  (for  an 
Apple  computer)  that  was  primarily 
designed  for  newsroom  prompting. 
The  computer  displayed  the  script  in 
large,  digital  letters  on  the  monitor 
under  the  two-way  mirror. 

The  computer  offered  several  ad- 
vantages over  the  old  systems.  It  was 
absolutely  silent,  the  letters  were  large 
and  legible,  and  changes  could  be 
made  with  a  couple  of  keystrokes. 
However,  this 
Apple  pro- 
gram never 
really  caught 
on.  A  pro- 
gram  written 


gramming  and  most  likely  would 
have  required  expensive  hardware 
changes. 

My  San  Francisco  company.  Magic 
Teleprompting,  currently  has  three  of 
these  Atari-based  teleprompters.  Each 
unit  consists  of  a  130XE,  a  1050  disk 
drive,  a  color  video  monitor  and  a 
special  hand  controller  that  connects 
to  the  joystick  port.  The  prompter 
software  itself  is  a  proprietary  pro- 
gram sold  by  Lynn  Greenberg  of  Elec- 
tronic Teleprompting  in  Newhall,  Cal- 
ifornia. One  of  ray  systems  includes 
an  Epson  printer  connected  through 
an  850  interface. 

We  send  prompters  up  and  down 
the  West  Coast,  each  system  packaged 


taking  out  any  strange  characters,  and 
then  transfer  it  to  the  Atari. 

I  do  the  transfer  with  a  null  modem 
adaptor  connected  from  the  Mac  to 
an  850  interface.  On  the  Mac  I  use  Red 
Ryder  10.3  and  on  the  Atari  I  use 
Backtalk  1.2  from  the  Antic  Arcade 
Catalog.  By  utilizing  the  XMODEM 
transfer  protocol,  1  can  make  error- 
less 2400  baud  transfers. 

The  Atari  system  has  proven  to  be 
quite  dependable.  Shipped  by  air 
freight  all  along  the  West  Coast,  these 
computers  have  been  through  rain, 
sleet  and  snow  —  and  they've  been 
dropped,  dragged,  or  bounced  onto 
the  film  set.  I  had  to  have  a  disk  drive 
aligned  once,  so  I  sent  it  to  the  Com- 
puter Support  company  in  South  San 
Francisco.  It's  worked  fine  ever  since. 

Many  corporate  executives,  actors, 


for  the  Atari  was  the  first  computer 
prompter  system  that  made  big  in- 
roads into  the  film  and  video  industry. 

An  Atari  800  with  a  customized  lan- 
guage cartridge  was  the  first  highly 
successful  computer  prompter  The 
Atari  offered  many  advantages  over 
other  systems.  Its  built-in  graphics 
abilities  made  it  easier  to  get  color,  dif- 
ferent font  sizes,  and  most  ixnportant, 
a  smooth  scroll — allowing  the  letters 
of  the  script  to  flow  smoothly  up  and 
down  the  screen  without  any  jerking 
or  jumping. 

The  Atari  also  had  a  built-in  NTSC 
video  port,  so  it  could  feed  the  im- 
age to  the  video  monitor  without  ad- 
ding expensive  video  cards  or  other 
interfaces.  Using  a  different  computer 
would  have  required  complex  pro- 


tightly  in  shipping-quality,  profes- 
sional cases.  Open  the  case,  plug  it  in, 
boot  up,  and  it's  ready  to  prompt. 

I  also  have  a  system  set  up  in  my 
office  for  entering  scripts  that  are  de- 
livered to  me  before  the  shoot  day.  I 
can  either  type  the  script  directly  into 
the  Atari,  or,  more  and  more  fre- 
quently, the  client  delivers  me  a  disk 
with  the  script  on  it.  The  disk  is 
usually  in  either  IBM  or  Macintosh 
format.  In  these  cases,  I  read  the  file 
into  my  Macintosh  SE,  massage  it  by 


tresses  and  politicians  unknowingly 
..ave  the  Atari  I30XE  to  thank  for 
making  their  lines  and  speeches  eas- 
ier and  more  comfortable  to  present. 

And  we  at  Magic  Teleprompting 
have  the  130XE  to  thank  for  making 
us  the  biggest  and  most  successful 
prompter  service  in  Northern  Cali- 
fornia.

TYPO  II  AUTOMATIC  PROOFREADER 

TYPO  II  automatically  proofreads  Antic's  type-in  BASIC  listings.  Type  in  the  listing  below  and  SAVE  a  copy  to  disk 
or  cassette.  Now  type  GOTO  32000.  At  the  prompt,  type  in  a  single  program  line  without  the  two-letter  TYPO  II 
code  at  the  beginning.  Then  press  [RETURN]. 

Your  line  will  reappear  at  the  bottom  of  the  screen.  If  the  TYPO  II  code  does  not  match  the  code  in  the  magazine, 
then  you've  mistyped  your  line. 

To  call  back  a  previously  typed  line,  type  [*],  then  the  line  number,  then  [RETURN].  When  the  completed  line  ap- 
pears, press  [RETURN]  again.  This  is  how  TYPO  II  proofreads  itself. 

To  LIST  your  program,  press  [BREAK]  and  type  LIST.  To  return  to  TYPO  II,  type  GOTO  32000.  To  remove  TYPO 
II  from  your  program,  type  LIST  "D:FILENAME",0,31999,  then  [RETURN],  then  NEW,  then  ENTER  "D:FILENAME", 
then  [RETURN].  Now  you  can  SAVE  or  LIST  your  program  to  disk  or  cassette.
